Linearized form effect on estimation adsorption parameters of three industrial dyes by lignocellulosic sorbent.

Textile industries discharge large amounts of untreated colored wastewater into ecosystems which have adverse effects on the human, living and aquatic environment. The aims of this study were: upgrading and testing the brewery waste adsorption affinity towards BEMACID red (B-R), BEMACID yellow (B-Y) and BEZAKTIV black (B-B), verified the effect of linear form modeling on adsorption parameters values and to find the limiting kinetic step in adsorption process. The adsorption efficiency of brewery waste towards three textile dyes: B-Y, B-R and B-B is tested. The evolution between the adsorption capacity and the operating conditions such as: pH solution, adsorbent mass, contact time and initial dye concentration is determined by kinetics measurements. Effect of a form of pseudo-first order, six forms of pseudo-second order, a form of intra-particle diffusion and a form of external mass transfer diffusion are tested to the prediction of kinetic parameters and to find the limiting kinetic step. In order to modeling the equilibrium data, a form of Freundlich and five forms of Langmuir isotherms are tested. The residual concentration of dye in solution was measured by spectrophotometer. Scanning Electron Microscope (SEM) was using to investigate the structure of raw adsorbent. The results of kinetics measurements show that the perfect adsorption operating conditions are: acidic medium for all dyes (pH = 2 and pH = 3), low mass adsorbent (m = 40mg), equilibrium time t = 40min and for initial concentration of 250mg/L. Also the results prove that the adsorption mechanism is controlled by both steps of diffusions (interne and extern diffusion) and fitted well by the first and the second linearized form of pseudo-second order model with correlation coefficient R2 = 0.99. The results of isotherms modeling show that the second and the third linearized forms of Langmuir giving the best removed amount for B-Y equal 200 and 219.4mg/g respectively compared to others linearized forms. In summary, the effect of linear forms used either in the medellization of isotherms or kinetic data is significant in the prediction of adsorption parameters, also brewery waste has a significant B-Y dye adsorption affinity compared to others dyes, the descending order of maximum adsorption capacity finding is: qe = 209mg/g for B-Y, qe = 152mg/g for B-R and finally qe = 108mg/g for B-B.

Influence of cationic doping at different sites in NaNbO3 on the photocatalytic degradation of methylene blue dye

The present study presents the preparation of Nb-based perovskite with different cationic dopants (potassium and vanadium) for the catalytic photodegradation of methylene blue (MB) dye. For the preparation of powder samples, chemical route followed by heat treatment (at 800 °C) was adopted and X-ray diffraction confirmed the phase formation. Furthermore, scanning electron microscopy (SEM/EDX) and X-ray photoelectron spectroscopy supported the successful incorporation of dopants in NaNbO3 lattice. Furthermore, the induced lattice distortion and resulted optical modification were determined by uniform strain model and UV–visible spectroscopy, respectively. As a result of inclusion of dopants, photodegradation of MB dye under household CFL exposure has been studied in detail by considering the different dye concentrations (1, 5, and 10 mg/L). Doping at both sites (A and B) in NaNbO3 exhibited better photocatalytic efficiency (34%) in 5 h of illumination as compared to single cation-doped systems which can be associated to the higher content of lattice defects (as charge trap centers), reduced optical band gap and oxygen vacancies. Furthermore, intraparticle diffusion model suggested that low concentration of dye solution exhibited surface diffusion mechanism, while higher concentration followed boundary layer diffusion mechanism for the photodegradation of MB dye.

Regenerable chitosan-bismuth cobalt selenide hybrid microspheres for mitigation of organic pollutants in an aqueous environment

Degradation of hazardous organic pollutants like dyes by semiconducting materials has been considered as one of the dynamic solutions for wastewater treatment. Herein, novel bismuth cobalt selenide (BCSN) tri-composite nanoparticles were prepared with a crystalline structure and narrow bandgap of (2.48 eV). The prepared nanoparticles were embedded in chitosan microspheres to avoid leaching and ensure the easy recovery of the composite. FTIR studies confirmed the synthesis of nanoparticles and chitosan‑bismuth cobalt selenide hybrid microspheres (BCSN-CM). SEM images showed the smooth face morphology having an average nanoparticles size of 30 nm and an average microspheres size of 734 μm. The crystallite size of the nanoparticles was also verified using the XRD technique and found to be 21.3 nm by applying Scherer's equation. EDX result demonstrated the presence of bismuth, cobalt, and selenium in the prepared sample. Congo red dye (CR) was degraded using the prepared BCSN-CM in sunlight irradiation, and operational parameters were evaluated to optimize the conditions responsible for maximum dye degradation. It was found that degradation of dye depends on factors like catalyst amount, irradiation time, dye concentration, and pH of dye solution. The degradation efficiency of prepared microspheres was found to be 85% of the 90-ppm solution under optimized conditions in sunlight irradiation for 100 min. The first-order kinetics was well fitted to degradation of CR having a rate constant of 1.50 × 10−2 min−1. Moreover, the prepared sample gave an excellent result after regeneration and reused up to five cycles. The newly fabricated chitosan-bismuth cobalt selenide hybrid microspheres might display a high potential for the removal of organic pollutants from the dye and textile industries wastewater.

Surface treated acid-activated carbon for adsorption of anionic azo dyes from single and binary adsorptive systems: A detail insight

Current study deals with the surface modification of acid activated carbon (prepared from Pongamia pinnata shells) with Cetyltrimethylammonium bromide (CTAB) and its role as an adsorbent in eliminating anionic azo dyes viz. Congo red (CR) and Direct blue 6 (DB) from single and binary adsorptive systems. Binary adsorptive system involved the synergistic and antagonistic influence of one dye over the adsorption of other dye. Physico-chemical alterations due to surfactant modification and post adsorption were studied using atomic force microscopy (AFM), Zeta Potential, scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDS), surface area analysis and Fourier-transformed infrared spectroscopy (FTIR). Process parameters influencing efficient adsorption of CR and DB species viz. initial pH of dye solution, adsorbent dosage, incubation temperature and initial concentration of dye species were optimised. Sorbate-sorbent interaction studies for single adsorptive system revealed sorbate’s monolayer formation over adsorbent’s surface and the involvement of chemisorption, as verified by Langmuir isotherm model and pseudo-second order model, respectively. Langmuir maximum adsorption capacity of the adsorbent was 555.56 mg/g for CR and 625.00 mg/g for DB. Meanwhile, for binary adsorptive system, competitive Langmuir model verified both CR and DB had antagonistic/competitive effect over each other’s adsorption. Thermodynamic analysis revealed the adsorptive process as exothermic, spontaneous and thermodynamically favourable with an elevated degree of dis-orderedness. Co-existing cations and anions has nominal effect on the adsorption capacity of dyes. Recyclability studies verified a modest efficiency of 62.52% for CR and 50.47% for DB species after the end of 4th adsorption-desorption cycle; thus affirming its recyclability potential. Phytotoxic assay affirmed the effectivity of the adsorbent in adsorbing dye species from aqueous solutions using Vigna mungo seeds as the model.

Functionalized polyurethane sponge based on dopamine derivative for facile and instantaneous clean-up of cationic dyes in a large scale

Functionalized sponge adsorbent was prepared by a mussel-inspired strategy, which achieved successive modification of material and remained the properties of substrate. The dopamine derivative, DOPAm, was synthesized and adhered to polyurethane (PU) sponge before in situ polymerization with sodium p-styrenesulfonate. The adsorbent showed superior removal efficiency for cationic dyes (98.9 % for methylene blue (MB) at the concentration of 200 μmol/L); it took 1 s only for the adsorbent to adsorb the dyes by swelling and squeezing out the bulk solution simply. Meanwhile, the superior adsorption effect of the adsorbent could be maintained in a wide range of solution pH values from 1 to 13 at room temperature (293 K) in several repeat experiments, due to the slight influence of strong acid and alkali on polysulfonate. With unchanged other experimental conditions, the removal efficiency is still more than 90 % after reusing for 10 times at the different concentrations of MB dye solutions (50, 100, 200 μmol/L). For large-scale wastewater treatment, with the removal efficiency of 80.0 %, the adsorbent could purify 4.1 L wastewater containing MB dye (100 μmol/L) with the maximum flux of 22.2 L/(m3·s) without the assistance of any equipment except for a vacuum pump. Therefore, the adsorbent has great possibilities to be applied in high-efficient and convenient treatment of wastewater in a large scale.

High-Performance Polyimides with Pendant Fluorenylidene Groups: Synthesis, Characterization and Adsorption Behaviour

High-performance polyimides (HPIs) were synthesized using various aromatic dianhydrides and fluorenylidene containing diamine via two-step polycondensation method and used as an adsorbent for the removal of dyes (Methylene blue (MB) and Rhodamine-B (Rh-B)). Various functional moieties (–O–, –(CF3)2, –(CH3)2) were incorporated through synthesis in the HPIs back-bone using various aromatic dianhydrides, which enhance the adsorption capacity of adsorbent. The structure and functional groups of HPIs were confirmed by NMR and FT-IR analysis. The surface morphology of HPIs and dye adsorbed-HPIs were determined using SEM–EDX analysis. The solution dye concentration was examined using a UV/Visible spectrometer. Adsorption parameters such as solution pH, initial dye concentration, adsorbent dosage, contact time and temperature were optimised. The effect of contact time and initial dye concentration data were used to evaluate the adsorption kinetic and isotherm parameters respectively. Types and mechanism of the adsorption process were predicted using adsorption kinetics and isotherm parameters. Adsorption of dye onto HPIs followed pseudo second-order kinetic model which was confirmed by the adsorption kinetic result. The maximum monolayer adsorption capacity (qe) of HPIs was calculated. From thermodynamic study, ΔG°, ΔS° and ΔH° were calculated, which could predict the nature of the adsorption process with respect to temperature. Adsorbed-HPIs waste was converted into a PET-adsorbed-HPIs composite to reduce the hazardous solid waste and examined the dye leaching properties.

An experimental technique has been developed aimed at determining a dependence of the distribution of Rhodamine G concentration in a water solution flow in a glass channel. It has been demonstrated that in the water flow moving in the glass channel, a stationary pattern of the distribution of solution concentration in water along the channel is established. The dye concentration is distributed uniformly over the channel due to molecular diffusion.

Carbonized Lanthanum-Based Metal-Organic Framework with Parallel Arranged Channels for Azo-Dye Adsorption.

In this contribution, the synthesis of the metal−organic framework (MOF) based on lanthanum that exhibits trigonal prism shape is presented. The length of a single side of this structure ranges from 2 to 10 μm. The carbonized lanthanum-based organic framework (CMOF–La) maintained the original shape. However, the lanthanum oxide was reshaped in the form of rods during the carbonization. It resulted in the creation of parallel arranged channels. The unique structure of the carbonized structure motivated us to reveal its adsorption performance. Therefore, the adsorption kinetics of acid red 18 onto a carbonized metal−organic framework were conducted. Various physicochemical parameters such as initial dye concentration and pH of dye solution were investigated in an adsorption process. The adsorption was found to decrease with an increase in initial dye concentration. In addition, the increase in adsorption capacity was noticed when the solution was changed to basic. Optimal conditions were obtained at a low pH. Kinetic adsorption data were analyzed using the pseudo-first-order kinetic model, the pseudo-second-order kinetic model and the intraparticle diffusion model. The adsorption kinetics were well fitted using a pseudo-second-order kinetic model. It was found that the adsorption of anionic dye onto CMOF–La occurs by hydrophobic interactions between carbonized metal-organic framework and acid red 18.

Effectiveness of Using Trichoderma viride as Biosorbent for Remazol Brilliant Purple in Batik Wastewater Treatment

S ynthetic dyes used in the batik industry cause negative impacts to the environment. One type of synthetic dyes used in batik industry is remazol brilliant violet. This synthetic dye is reactive, carcinogenic, and non-biodegradable. Therefore, a strategy to degrade this synthetic dye is needed. In this study, the potential application of Trichoderma viride for biosorption of remazol brilliant violet (RBZ) in batik wastewater was investigated. The current work aimed on determination of the optimum biosorption conditions, including pH, contact time, and RBZ concentration. Biosorption of RBZ were carried out at pH 4 to 9; with contact times of 12, 24, 30, 36, and 42 h, with concentrations of dye solutions were 40, 60, 70, 80, and 90 mg/L. Results showed that the optimum biosorption of RBZ was obtained at pH 4, for 30 h, and optimum concentration of RBZ at 60 mg/L, with the RBZ absorbed was 79.27%. The FTIR analysis suggested that RBZ biosorption changed the chemical functional groups in the T. viride. The FTIR spectra revealed that the biomolecules that are affected during the process of biosorption were mainly lipids and proteins, and slightly from nucleic acids and carbohydrates.

Graphene Oxide Nanofiltration Membranes Containing Silver Nanoparticles: Tuning Separation Efficiency via Nanoparticle Size.

Three types of graphene oxide/silver nanoparticles (GO/AgNPs) composite membranes were prepared to investigate size-effect of AgNPs on nanofiltration ability. The size of AgNPs was 8, 20, and 33 nm, which was characterized by UV-visible spectroscopy and transmission electron microscopy. The morphology and structure of GO and GO/AgNPs composite membranes were characterized by atomic force microscopy, scanning electron microscopy, and X-ray diffraction. The filtration performance of membranes were evaluated on a dead-end filtration device. When the size of AgNPs is 20 nm, the GO/AgNPs composite membrane has the highest water flux (106.1 L m−2 h−1 bar−1) and rejection of Rhodamine B (RhB) (97.73%) among three types of composite membranes. The effect of feed concentration of dye solution and the flux of common solvent was also investigated. The mechanism was discussed, which demonstrated that both interlaying spacing and defect size influence the filtration ability of membrane, which is instructive to future study.

Macropore–matrix mass transfer of reactive solutes quantified by fluorescence imaging

AbstractHorizontal infiltration experiments with a fluorescent dye (e.g., Na‐fluorescein) potentially allow the quantification of the macropore–matrix mass transfer of reactive solutes through coated macropore surfaces. The objectives were (a) to determine the movement and map the spatial mass distributions of a reactive and fluorescent dye (i.e., Na‐fluorescein) at the millimeter scale during horizontal tracer application to the intact structural surface of a soil aggregate, and (b) to validate the method by comparing total masses as quantified with Fluorescence imaging with total applied dye masses. For the quantification of dissolved masses of dye, millimeter‐scaled distributed water contents obtained from horizontal flow simulation using Hydrus‐1D were multiplied with mapped dye solution concentrations. The spatial distribution of dye concentrations was visualized and quantified with a fluorescence imaging technique at a pixel resolution length of ∼100 μm. Submillimeter‐scaled distribution maps of adsorbed dye concentrations were derived using the calibrated Freundlich adsorption model. The sorption isotherm predicted that most of the dye was adsorbed to soil. In total, 1,366 μg of dye was transferred through the coated matrix block, of which 1,181 μg was adsorbed to soil. The applicability of the method was validated by comparing applied and recovered Na‐fluorescein masses, which corresponded relatively closely. Although the test of the approach presented here was limited by uncertainties regarding the local distributions of water contents and bulk density, the method could be applied to map two‐dimensional horizontal distributions of dye in an intact soil clod for quantifying macropore–matrix mass transfer of the reactive solute.

Cellulose nanocrystals-based flocculants for high-speed and high-efficiency decolorization of colored effluents

Abstract The modified cellulose nanocrystals (CNCs) are expected to achieve fast and efficient decolorization of colored effluents. In this study, CNCs were surface-modified by grafting polymerization of acryloyloxyethyltrimethyl ammonium chloride (AETMAC) with the initiator of ceric ammonium nitrate (CAN). The optimum scheme to synthesize poly acryloyloxyethyltrimethyl ammonium chloride) (PAETMAC)-grafted CNCs (PAETMAC-g-CNCs) with the highest cationicity of 31.2% was determined from the orthogonal test as 4/1 (w/w) of AETMAC/CNCs, 0.01 mg/L of CAN, 50 °C and 5 h. Zeta potential, particle size, FT-IR and 13C-NMR characterizations manifested the successful introduction of PAETMAC on CNCs. XRD proved the same cellulose I of PAETMAC-g-CNCs as CNCs. As new eco-friendly flocculants, PAETMAC-g-CNCs were tested to decolorize 100 mg/L of neutral reactive blue 19 (RB 19) solutions. The results show that the higher the cationicity of PAETMAC-g-CNCs is, the less amount is needed for getting the maximum color removal. The widest flocculation window from 30 to 100 mg/L is acquired using PAETMAC-g-CNCs2 with the medium cationicity of 21.1%. Moreover, PAETMAC-g-CNCs2 is less sensitive to the pH and ion concentration of dye solutions due to its increased colloidal stability in electrolytes, acids and/or bases. It can work on a wide pH range and is applicable to treat high salt concentration effluents. The color removal efficiency is over 80% at pH 3–9 and NaCl concentration up to 60 g/L. The high crystallinity of PAETMAC-g-CNCs2 and the PAETMAC grafts promote the growth of dye-containing flocs and accelerate the flocs’ precipitation. PAETMAC-g-CNCs2 can rapidly decolorize the RB 19 solutions, which is desirable for industrial applications.
