Rapid analysis of anionic and cationic surfactants in water by paper spray mass spectrometry.

The discharge of wastewater containing surfactants and other industrial pollutants is contaminating the world's water resources which should be taken seriously. This paper describes a paper spray mass spectrometric (PS-MS) method for rapid and quantitative analysis of anionic and cationic surfactants in water samples. Eight cationic surfactants and four anionic surfactants can be simultaneously determined in positive or negative mode without sample pretreatment and chromatographic separation. The PS-MS analysis time was only 10 s. Under optimized conditions, the method presented a suitable linear range (1-80 μg mL-1, linear regression coefficients (R2) higher than 0.995 for cationic surfactants, R2 higher than 0.990 for anionic surfactants), a low limit of detection (0.05-0.35 μg mL-1 for cationic surfactants and 0.20-0.35 μg mL-1 for anionic surfactants), and satisfactory recovery values (97.3-106.1%). The method validation indicated that the method precision and accuracy were satisfactory. The results demonstrated that PS-MS is especially suitable for the high-throughput analysis of surfactants in water samples.

Unveiling the phase behavior of CiEj non-ionic surfactants in water through coarse-grained molecular dynamics simulations.

Poly(oxyethylene) alkyl ethers, usually denoted by CiEj surfactants, exhibit a rich phase behavior in water, self-assembling to form a variety of 3-D structures with a controllable morphology that find multiple applications across different industrial segments. Hence, being able to describe and understand the effect of molecular structure on the phase behavior of these systems is highly relevant for the efficient design of new materials and their applications. Considering the promising results obtained over the last decade using the MARTINI model to describe ethylene-oxide containing compounds, an extensive assessment of the ability of such a model to describe the phase behavior of CiEj in water was carried out and results are presented here. Given the overall poor temperature transferability of the MARTINI model, mostly due to the lack of an accurate representation of hydrogen bonding, simulations were carried out at a single temperature of 333 K, where most phases are expected to occur according to experiments. Different chain lengths of both the hydrophobic and hydrophilic moieties, spanning a wide range of hydrophilic-lipophilic balance values, were investigated and the phase diagrams of various CiEj surfactants explored over a wide concentration range. The model was able to satisfactorily describe the effect of surfactant structure and concentration on mesophase formation. The stability and dimensions of the obtained phases, and the prediction of some unique features such as the characterization of a singular lamellar phase are presented. The results obtained in this work highlight both the predictive ability and the transferability of the MARTINI forcefield in the description of such systems. Moreover, the model was shown to provide adequate descriptions of the micellar phase in terms of micelle dimensions, critical micelle concentration, and average aggregation number.

An experimental investigation of hydrodynamic and heat transfer characteristics of surfactant-water solution and CNT nanofluid in a helical coil-based heat exchanger

Nanofluids are gaining attention due to their excellent heat transfer characteristics as compared to conventional basefluids. In this study, CNT nanofluid was prepared using double distilled water (as basefluid) and mixed surfactant (a mixture of surfactant SDBS and GA) keeping the Surfactant/CNT ratio 1. Hydrodynamics as well as heat transfer characteristics of water, surfactant-water solution and CNT nanofluid were investigated in coil tube heat exchanger. Thermo-physical properties of surfactant-water solution and CNT nanofluid were also examined. Results showed no difference in viscosity of surfactant-water solution in comparison to water but a slight increment in density of the surfactant-water solution compared to water. Also, it was found that friction factor was increased with increase in Reynolds number for water, surfactant-water solution and CNT nanofluid. The overall heat transfer coefficient was 62.62% higher for CNT nanofluid at 5000 Reynolds number as compared to water. No enhancement was observed in heat transfer coefficient for surfactant-water solution in comparison to water. These results concluded that CNT nanoparticles play a major role to enhance the heat transfer rate of nanofluid in contrast to water.

Study on the mechanism of polyethylene oxide groups improving the foamability of anionic surfactants in hard water

Improving the foamability of anionic surfactants in hard water is essential to reduce the adding concentration and economic cost of foaming agents for dust control. In this work, sodium dodecyl sulfate (SDS) and sodium dodecyl ether sulfate (SDES) were selected to explore the mechanism of polyethylene oxide (EO) groups improving the foamability of anionic surfactants in hard water by experiments and molecular dynamics simulations. The experimental results show that SDES containing EO groups has better foaming performance in hard water compared with SDS. The simulation results indicate that the presence of EO groups can inhibit the combination of SO4− groups and Ca2+ ions at the air/water interface, which makes part of Ca2+ ions migrate from the interface layer to the bulk water. In addition, EO groups attract some Ca2+ ions to distribute around them, thereby further reducing the number of Ca2+ ions combined with SO4− groups, which helps to improve the surface activity and foamability of anionic surfactants in hard water. An increase in the number of EO groups can enlarge the interfacial thickness and the number of hydrogen bonds between surfactants and water molecules, enhancing the strength of bubble film. Moreover, the farther the EO group is from the SO4− group, the smaller the contribution to the hydration of anionic surfactants.

Characteristics and Behavior of Different Catalysts Used for Water Decontamination in Photooxidation and Ozonation Processes

The objective of this study was to summarize the results obtained in a wide research project carried out for more than 15 years on the catalytic activity of different catalysts (activated carbon, metal–carbon xerogels/aerogels, iron-doped silica xerogels, ruthenium metal complexes, reduced graphene oxide-metal oxide composites, and zeolites) in the photooxidation (by using UV or solar radiation) and ozonation of water pollutants, including herbicides, naphthalenesulfonic acids, sodium para-chlorobenzoate, nitroimidazoles, tetracyclines, parabens, sulfamethazine, sodium diatrizoate, cytarabine, and surfactants. All catalysts were synthesized and then texturally, chemically, and electronically characterized using numerous experimental techniques, including N2 and CO2 adsorption, mercury porosimetry, thermogravimetric analysis, X-ray diffraction, Fourier-transform infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, diffuse reflectance UV–vis spectroscopy, photoluminescence analysis, and transmission electron microscopy. The behavior of these materials as photocatalysts and ozonation catalysts was related to their characteristics, and the catalytic mechanisms in these advanced oxidation processes were explored. Investigations were conducted into the effects on pollutant degradation, total organic carbon reduction, and water toxicity of operational variables and the presence of different chemical species in ultrapure, surface, ground, and wastewaters. Finally, a review is provided of the most recent and relevant published studies on photocatalysis and catalyzed ozonation in water treatments using similar catalysts to those examined in our project.

Microextraction-colorimetric determination of anionic surfactants in natural and waste waters

An eco-friendly, simple, rapid and cheap method for determining anionic surfactants in natural and waste waters by microextraction-colorimetric method has been developed. The essence of the proposed approach consisted in extraction and concentration of analytes in an acidic medium in the form of associates with organic reagents (methylene blue and acridine yellow) by dispersion liquid-liquid microextraction using a mixture of chloroform-acetonitrile as an extracting and dispersing solvent, followed by aggregation of extractant microparticles by centrifugation and subsequent measurements of color characteristics using a smartphone. The values of the basic components of the RGB colorimetric system were used as an analytical signal to calculate the final color: The selection of optimal conditions for microextraction concentration of anionic surfactants from natural waters (the nature of the extracting and dispergating solvents, the volume of the dispergating solvent) was performed for the sodium dodecyl sulfate — methylene blue system. To study the colorimetric characteristics of the prepared extracts, a smartphone «iPhone X» was used as a color-registering device equipped with a specialized software product «RGBer». To minimize the measurement error by fixing the distance to the object under study and lighting conditions, we propose an installation that increases the accuracy and sensitivity of the determination and makes the method more mobile. The total content of the most common components of detergents was determined: sodium dodecyl sulfate, sulfonol, laureth sulfate and disodium laureth-3-sulfosuccinate. The detection limits ranged within 0.01 – 0.02 and 0.05 mg/liter. The range of detectable contents for all analytes was 0.05 – 1.0 mg/liter. For the determined surfactants, the equations of the relationship between the analytical signal and the concentration were obtained. The calibration graphs are linear with coefficients of the approximation reliability ≤0.98. The correctness of the method was tested on samples of natural water using the spike test procedure. The relative standard deviation of the analysis results does not exceed 0.13. The analysis duration is 20 – 30 min.

Interplay between surfactant self-assembly and adsorption at hydrophobic surfaces: insights from dissipative particle dynamics

ABSTRACT We study the self-organisation of aqueous surfactants in bulk phase, and the adsorption and self-organisation of the aqueous surfactants at a planar hydrophobic surface by dissipative particle dynamics. Nonionic surfactants, n-alkyl poly(ethylene oxide) CE, and water are coarse-grained into mesoscopic beads comprising 1–3 heavy atoms and two water molecules, respectively. The size of the mesoscopic beads is related to the molar volume of the underlying molecular fragments while the bead–bead interaction parameters are calibrated against the water-octanol partition coefficients. We focus on the CE, CE, CE, and CE surfactants in water that form spherical micelles in the bulk. The bulk micellization is primarily affected by the alkyl tail length which is demonstrated by an order of magnitude decrease in the critical micelle concentration when going from the aqueous CE to aqueous CE solutions. Surfactants strongly adsorb on the hydrophobic surface, adopting lying-down configurations and forming hemispheres which are in equilibrium with the spherical micelles in the bulk. In contrast to the bulk phase, the surfactant adsorption behaviour is influenced by both the alkyl tail and head chain lengths.

Partitioning of Selected Anisole and Veratrole Derivatives between Water and Anionic Surfactant Micelles.

The UV absorption spectra of six structurally related derivatives of anisole and veratrole, i.e., anisaldehyde, (E)-anethole, estragole, veratraldehyde, methyleugenol and (E)-methylisoeugenol, were recorded at various concentrations of the anionic surfactants, either sodium lauryl sulfate (SLS) or sodium lauryl ether sulfate (SLES) at T = 298 K. In addition, conductivity and density measurements were made for the SLS and SLES solutions to determine the volumetric properties of the studied surfactants. Next, using the W. Al-Soufi, L. Pińeiro and M. Novo model (APN model) including the pseudo-phase model for micellar solubilization, the values of micelle-water partition coefficients for each perfume-surfactant system were determined. In addition, the relations between the molecular structures of the solute and the head group of the surfactant and the value of the micelle-water partition coefficient as well as the octanol-water one were discussed.

One-pot Pseudo-Domino Three-Component Knoevenagel Condensation Reaction in Water Enabled by Micellar Catalyst: Mechanism and Reactivity

The micellar catalysis is well-known for its hydrophobic effect that is the tendency of nonpolar groups to cluster within the lipophilic core so as to shield them from contact with an aqueous environment formed upon the dissolution of a surfactant in water. This provides a unique opportunity to establish organic transformations in greener solvents, such as water leading to organic waste control and easy product isolation protocols. Considering the significant interaction of thiobarbituric acid moieties in a biological macromolecule core, herein, a highly efficient procedure for the synthesis of biological and medicinal important 5-(arylmethylene)dihydro-2-thioxo-4,6(1H,5H)-pyrimidinediones via Knoevenagel condensation of thiobarbituric acids and aldehydes catalyzed by a surfactant, sodium dodecyl sulfate, is developed. The synthetic procedure shows the excellent activity of the micellar catalysts towards the aldehyde activation leading to a facile condensation. The application of the method is demonstrated by further synthesis of 5,5'-(4-arylmethylene)bis[dihydro-2-thioxo-4,6(1H,5H)- pyrimidinediones]. Theoretical studies of the reaction were also carried out to investigate the effect of electron releasing and electron-withdrawing group in benzaldehyde on the reaction.

Copolymer Based on Polyglycerol-Acrylate-Lactate as Potential Water Viscosifier and Surfactant for Enhanced Oil Recovery

Polymer and surfactant flooding are widely applied processes in enhanced oil recovery (EOR) in which viscous polymers or surfactants aqueous solutions are introduced in oil reservoirs to rise the recovery of the remaining oil. In this regard, one of the challenges of EOR practices is the use of efficient but low-cost viscosifier and surfactant polymers. This work is aimed at synthesizing a polyglycerol derived from the biodegradable and nontoxic monomer, glycerol, and evaluating the effect of its copolymerization on rheological and interfacial properties, which were tested in water and brine for the former and in the water/oil system for the last properties. The copolymers were synthesized using a polyglycerol backbone, acrylic acid, lactic acid, and oleic acid. The chemical structure of copolymers was characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetry (TG), and differential scanning calorimetry (DSC). The viscosity and the interfacial tension (IFT) of polymeric solutions were tested. Thus, the viscosity and surface performance of the prepared polymer solutions in distilled water and brine were analyzed according to the structure of the synthesized polymers. The results showed that the synthesized polymers modified water viscosity and surface tension between water and oil. The developed polymers could be candidates for applications in enhanced oil recovery and related applications.

Experimental study on pool boiling regime transitions of vertical rod quenched in aqueous surfactant solutions using inverse heat transfer analysis

In this study, the effect of surfactants and liquid temperature on boiling regime transitions of high-temperature rod during quenching was examined using inverse heat transfer analysis. Liquid pools of the aqueous sodium dodecyl sulfate (SDS) and Triton X-100 solutions were used with pure water. In the present experimental range, the critical heat flux (CHF) and minimum film boiling (MFB) point for all test fluids increased as the liquid temperature decreased. On the other hand, the SDS and Triton X-100 surfactants suppressed the CHF and MFB point, which might be due to the enhancement of vapor film stability caused by reduced surface tension. Some previous experimental studies have reported that the surfactants enhance the boiling regime transitions, but their results seem to be contradictory to the present ones. Considering the present study with the previous works, the surfactants seem to have different effect on boiling phenomena depending on the boiling regime. In other words, in the aqueous surfactant solution, the boiling regime transition points seem to be markedly influenced by a path of boiling regime. In addition, boiling mode diagrams were presented for pure water and aqueous surfactant solutions.

Study of conductivity, contact angle and surface free energy of anionic (SDS, AOT) and cationic (CTAB) surfactants in water and isopropanol mixture

The thermodynamic properties of cationic surfactant CTAB (cetyltrimethylammonium bromide), anionic surfactant SDS (sodium dodecyl sulfate), and AOT (Aerosol OT) in pure water and 0.1, 0.2, 0.3, and 0.4 volume fraction of isopropanol were observed by measuring the conductivity at 298.15 K. Various physicochemical properties like CMC, α and the thermodynamic properties like standard free energy of micellization (∆Gmo), the free energy of surfactant tail transfer (∆Gtranso) were calculated. Also, (log S1 and log S2), α, CMC, K0KCMC, ∆Gmo and ∆Gtranso are correlated with the volume fraction of isopropanol. The result revealed a sharp increase in conductivity with an increase in surfactant concentration. With the increasing isopropanol content in the solvent composition, the critical micelle concentration (CMC) of the CTAB and SDS increased. The degree of micellar dissociation (α) as well as the Gibbs' free energy was found to be increased with the increasing volume fraction of isopropanol. The correlation of ∆Gmo with the solvent parameters and the solvophobic parameter were also included. The contact angle and surface free energies over the aluminum foil surface were also evaluated using a drop shape analyzer (DSA-25E).

Pore scale experimental and numerical study of surfactant flooding for enhanced oil recovery

Surfactant flooding is a traditional method to enhance oil recovery. The surfactant flooding experiment based on glass etching model allows researchers to observe directly how the remaining oil is displaced by surfactant through microscope, so as to explore the mechanism of surfactant enhanced oil recovery. However, microscopic experiments mostly stay at the level of physical experiments, and the operation of physical experiments is too complex and cumbersome. This study is the first to combine surfactant flooding experiment with numerical simulation in glass etching model. Firstly, based on the real pore and throat structure of the real low permeability reservoir core, the glass etching model was developed, and the micro-oil-water displacement experiment was carried out. Through microscopic observation and analysis, combined with testing and image processing technology, the effect of water flooding was quantitatively investigated. Then the surfactant flooding was carried out. Three surfactants were used for displacement. It was found that residual oil in pore network was greatly reduced. The recovery factor has been greatly improved. Finally, numerical simulation of water flooding and surfactant flooding based on micro-physical experiment was carried out. The results of numerical simulation were compared with the experimental results. It is found that the recovery factor and the form of residual oil are basically the same. By analyzing the results of numerical simulation of oil recovery, it is found that the extent of surfactant enhancing oil recovery is different under different interfacial tension. The results showed that the surfactant with interfacial tension of 0.22 mN/m has the highest ability to enhance oil recovery. This work provides a reference for surfactant selection in oilfield development. It can select the best surfactant according to the factors of time, efficiency and cost.

Application of anionic surfactant∖engineered water hybrid EOR in carbonate formations: An experimental analysis

Abstract A hybrid enhanced oil recovery (EOR) method by combining low salinity water (LSW) and low salinity surfactant (LSS) flooding techniques was designed. Different experiments were done to screen the Caspian seawater (SW) with altered ionic composition and surfactant, for the optimized performance in Kazakhstani carbonate oil fields. Changing to a more water-wet state and creating the middle phase were studied as the main criteria to select the best-engineered brine and anionic surfactant. The largest alteration towards the water-wet condition was recorded at 10 times dilution of the SW with 3- and 6- times spiked calcium and sulfate ions, respectively (10xSW-6SO4, Mg, 3Ca). This combination of anionic surfactants with carbonate formations is considered as a new approach in hybrid EOR methods. Among the anionic surfactants screened, Soloterra-113H (Alkyl Benzenesulfonic acid) showed the best solubilization ratio, aqueous stability, and Winsor type 3 microemulsions. The wettability alteration by the combination of optimized brine and screened surfactant was greater compared to the standalone LSW, which was confirmed by the 10° difference in contact angle measurement. The microemulsion phase constituted nearly 40% of the total height of the oil/brine column by the hybrid method. The recovery factor after injecting formation water was 52%, and it increased to 61% after optimized LSW injection. After switching to the engineered brine/surfactant, the recovery factor reached 70%, which proves the effectiveness of the hybrid method. The proposed combined method works better than either standalone EOR method due to the higher alteration in capillary number by changing wettability and reducing IFT, which leads to higher oil recovery.

Measuring electrostatic charge on pneumatically generated spray drops

Activities such as the suppression of coal dust would benefit from an improved understanding about how the presence of surfactant alters the charge distribution of spray drops. However, there is no standard method to measure charge and size distributions of nozzle-generated spray drops. To fill this gap, a new spray drop charge measurement system was developed to measure a broad range of sizes and electrostatic charges for spray drops based on the principle that the free-falling drops can be separated according to their electrostatic mobility in an electrical field with known strength. High and low concentration (1 × 10−4 and 1 × 10−6 M, respectively) anionic, cationic, and nonionic surfactant sprays and water spray were tested. Nonionic and cationic surfactant-containing sprays and water spray carried net positive charge on average, while anionic surfactant-containing sprays tended to carry net negative charge on average. Increasing surfactant concentration did not increase the magnitude of drop charge among the tested surfactants. Drop charge level was significantly higher among larger size drops, with the average charge per particle on 320 μm drops 1000 to 10,000 times higher than on 20 μm drops. The spray drop charge measurement system developed in this study can be used to measure spray drops with an electrostatic charge ranging from 0 to 960,000 charges per drop and diameter ranging from 20 to 270 μm. Potential design improvements described in this study and additional computing power could improve measurement accuracy and precision, as well as the capacity of the system.

Stimuli-Responsive Biomass Cellulose Particles Being Able to Reversibly Self-Assemble at Fluid Interface.

Stimuli-responsive surface-active microcrystalline cellulose (MCC) particles are obtained by interaction with conventional cationic surfactants such as cetyltrimethylammonium bromide (CTAB) in aqueous media, where MCC are in situ hydrophobized by adsorption of the cationic surfactant in water via electrostatic interaction and with the in situ hydrophobization removed by adding an equimolar amount of an anionic surfactant such as sodium dodecyl sulfate (SDS). The trigger is that the electrostatic interaction between the oppositely charged ionic surfactants is stronger than that between the cationic surfactant and the negative charges on particle surfaces, or the anionic surfactant prefers to form ion pairs with the cationic surfactants and thus making them desorbed from surface of MCC. Reversible O/W Pickering emulsions can then be obtained by using the MCC in combination with trace amount of a cationic surfactant and an anionic surfactant, and the anionic surfactant with a longer alkyl chain is more efficient for demulsification. With excellent biocompatibility, biodegradability, and renewability, as well as low toxicity, the biomass cellulose particles that can be made stimuli-responsive and able to reversibly self-assemble at fluid interface become ideal biocompatible particulate materials with extensive applications involving emulsions and foams.

Design, synthesis, characterization, and surface activities of comb-like polymeric fluorinated surfactants with short fluoroalkyl chains

Compared to hydrocarbon surfactants, fluorinated surfactants exhibit excellent surface activity. But long-chain linear perfluoroalkyl derivatives containing more than six CFn units have raised environmental concerns because they are persistent, bio accumulative, and highly toxic. Therefore, the development of new, environmentally friendly fluorinated surfactants is urgently required. Given that shortening the fluorocarbon chains of fluorinated surfactants can enhance their environmental safety, we designed and prepared a series of novel comb-like polymeric fluorinated surfactants by means of one-step free-radical copolymerization reactions of fluorinated methacrylates (FMAs) as hydrophobic monomers (containing two, four, or six CF2 groups; denoted FMA-4, FMA-8, and FMA-12, respectively) and poly(ethylene glycol) methyl ether methacrylates (PEGMEMAs) as hydrophilic monomers (Mn = 300, 500, or 950 Da; denoted PEGMEMA-300, PEGMEMA-500, and PEGMEMA-950, respectively) with initiation by 2,2-azobis(2-methylpropionitrile). The resulting surfactants, designated poly(PEGMEMAm-FMAn)x, were characterized by 1H and 19F nuclear magnetic resonance spectroscopy, gel permeation chromatography, static surface tension analysis, dynamic light scattering and transmission electron microscopy. The surface activities of the surfactants could be regulated by adjusting the ratio of the hydrophilic and hydrophobic monomers. A result that differs from that for previously reportedly fluorinated surfactants, we found for the first time that under certain conditions, the surface activities of these short-fluorocarbon-chain surfactants exceeded the activities of long-fluorocarbon-chain surfactants. The lowest static surface tension achieved with these poly(PEGMEMAm-FMAn)x surfactants in water was 30.12 mN/m.

Electrochemical micropipette-tip for low-cost environmental applications: Determination of anionic surfactants through their interaction with methylene blue

Miniaturization is one of the main requirements in the design of portable devices that allow in-field analysis. This is especially interesting in environmental monitoring, where the time of the sample-to-result process could be decreased considerably by approaching the analytical platforms to the sampling point. We employed traditional mass-produced and low-cost elements (micropipette tips and pins) in an out-of-box application to generate an innovative and cost-effective platform for analytical purposes. We have designed simple and easy-to-use electrochemical cells inside polypropylene micropipette tips with three stainless-steel pins acting as the working, reference and counter electrodes of a potentiostatic system. The pin acting as working electrode was previously coated with carbon ink, meanwhile the rest were used unmodified. In this way, electrochemical in-the-tip measurements were done directly using low volumes (μL) of sample. The devices showed good reproducibility, with a relative standard deviation of 7% (n = 5) for five different tip-based complete electrochemical cells. As a proof-of-concept, its utility has been probed by the determination of an anionic surfactant (sodium dodecyl sulphate, SDS) in water through its interaction with methylene blue (MB). Two different alternatives were presented based on the: 1) increase in the current intensity of the cathodic peak of MB due to the presence of SDS; 2) electrochemical determination of the MB remaining in the aqueous phase after extraction of the pair SDS-MB to an organic medium.

Study on the Influencing Factors of the Emulsion Stability of a Polymeric Surfactant Based on a New Emulsification Device

Polymeric surfactant flooding is an effective method to improve oil recovery, and the stability of the emulsion is closely related to the effect of surfactant flooding. The preparation method for a surfactant-stabilized emulsion is relatively simple, and the emulsion produced by the existing device cannot simulate the real formation conditions. To better simulate the emulsification of polymeric surfactant during formation and to study the influencing factors of emulsion stability, a new sieve plate rotary emulsification device was used to prepare emulsions instead of the traditional high-speed shear emulsifier, and the stability of emulsions prepared by different methods was compared. The parameters of the device were optimized by determining the water content, particle size, and Turbiscan Stability Index TSI (stability parameter) of the emulsion. The factors affecting the stability of the emulsion were studied by using the optimized experimental device. The results showed that the optimized parameters of the sieve plate rotary emulsification device were 5 sieve plates, diameter of 1 mm, and emulsification time of 60 min. The stability of the emulsion prepared by the new device was better than that of the emulsion prepared by the traditional high-speed stirrer, which can be attributed to the more abundant contact and mix of oil and surfactant solution. Meanwhile, as the polymeric surfactant concentration, salinity, and water–oil ratio increased, the stability of the polymeric surfactant emulsion increased. The results of this study provide a theoretical basis and guidance for better simulation of polymeric surfactant migration and emulsification during formation.
