Emerging Contaminants Removal from Wastewater Using Organo-Modified Bentonite Clay

Organo-modified bentonite clay locally sourced from Bauchi State, Nigeria was prepared and used as an adsorbent for Emerging Contaminants (EC) capture from Kaduna Polytechnic female hostel wastewater. The produced adsorbent was characterized to determine the functional groups, surface area and crystal structure. Surface area for directly modified bentonite clay produced adsorbents and oxalic acid-pretreated bentonite clay adsorbent was found to be 625 m2/g and 349.2 m2/g respectively and the morphology of the produced acid-pretreated organo-modified bentonite clay adsorbents has better pore development with a higher amorphous structure. The wastewater compositions were found to contain major ECs identified to be Diclofenac, Triclosan, Methylparaben, and Bisphenol A, which account for 76.206% of the ECs that are detrimental to human and the environment. The impact of the adsorption factors; contact time, adsorbent dosage, and temperature on uptake behavior were all examined. Effect of adsorbent dosage was established which shows that all ECs removed rise rapidly from 0.5 – 1.0 g adsorbent dosage and then slowly reach a maximum of 98.65% Triclosan, 95.83% Diclofenac, 91.49% BPA, and 62.16% Methyl-Paraben removal as adsorbent dosage increases to 2g. On the other hand, as the adsorbent dosage increases to 3g, the removal rate of all ECs was observed to drop slightly and then attain maximum removal as the dosage rises to 4g. In contrast, a rise in adsorbent dosage of 2.5g gives a sudden drop in removal of Triclosane to 92.41% and Methyl-Paraben to 53.01% as well as a sharp drop in Methyl-Paraben to 33.33% and slightly drop in the removal of all other ECs. Langmuir and Freundlich isotherms models were fitted to the adsorption data and Freundlich showed best fit indicating chemisorption. The adsorption of triclosan, diclofenac, bisphenol A, and methylparaben followed pseudo second-order kinetic model.

Hardening mechanism of waste polyolefin mixtures in the presence of modified bentonite clay

The aim of the work is to obtain and study polymer composite materials based on mixtures of secondary polyolefins and modified polydisperse bentonite clay. The formation features of the structure of mixtures of waste polyolefins in the presence of this-type filler are studied. The data on the changes in the mechanical strength of mixed composites, as well as the results of physico-chemical studies are presented. Mixtures based on waste polymers in the presence of highly dispersed particles of modified polydisperse bentonite are characterized by the improvement of the strength of composites due to increased interfacial interaction in them and by the formation of structure uniformity of the material. This to some extent compensates for the loss of cohesive strength of secondary polymers due to thermal degradation processes. The following conclusions are made: at the phase boundaries, the molecular mobility of polymer chains decreases, which leads to changing the crystallization conditions and to appearing a nonequilibrium stress state; introducing bentonite increases crystalline due to the initiation of physico-chemical interaction; the strength grows due to increased interfacial interaction and structure uniformity; the formation mechanism of a complex of properties of composites consists of two-level adsorption – a modifier on filler particles and active polymer groups on the modified filler surface.

Removal of malachite green dye by sodium dodecyl sulfate modified bentonite clay: Kinetics, thermodynamics and isotherm modeling

Adsorption of malachite green (MG) onto sodium dodecyl sulfate (SDS) modified bentonite clay (MBC) was investigated. MBC was synthesized and characterized by X-ray diffraction (XRD), thermos-gravimetric analysis (TGA), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and Brunauer–Emmett–Teller (BET) Sorptometer. According to XRD analysis, the interlayer distance d-spacing increases from 1.2496 nm to 1.4000 nm after modification of bentonite clay (BC). TGA analysis suggests that the residual mass at 1198.4 °C is 92.74% which indicates that the MBC adsorbent is thermodynamically stable. BET analysis confirms that surface area decreases from 22.87 m2/g to 20.13 m2/g after modification. TEM, EDS and XPS analysis confirm the adsorption of MG onto MBC. The efficiency of this adsorbent for the uptake of MG was investigated using batch adsorption technique at various contact times, pHs, dye concentration, temperature, particle size, concentration of competitive ion and adsorbent dosage. Adsorption capacity rises as contact time, starting dye concentration and temperature increase, while decreasing when the particle size and competing ion concentration increase. The adsorption process follows the pseudo second order kinetics model over the pseudo first order kinetics model and the Elovich kinetics model. Compared to the Freundlich, Temkin and Dubinin–Radushkevich isotherm models, the Langmuir isotherm model provides greater insight into the adsorption process. The maximum adsorption capacity, qm was 1988.387 mg/g at optimum conditions (45 °C, pH 10, contact time 180 min, adsorbent dosage 200 mg/L) which was calculated from the Langmuir isotherm model. Negative values of free energy change, ΔG (−2.8464 kJ/mol at 30 °C) indicated spontaneity of the adsorption of MG onto MBC and The process is endothermic, as suggested by positive values of the heat of adsorption, ΔH (5.6514 kJ/mol). The value of activation energy (Ea = 9.7956 KJ/mol) and the estimated average free energy of adsorption (E < 8) supported that the adsorption process is physisorption.

Development and Characterization of Unmodified and Modified Natural Rubber Composites Filled with Modified Clay.

Novel composite based on rubber and modified bentonite clay (Clay) was investigated. The modified bentonite clay was developed by dispersing in ethanol solutions (Et-OH) using ultrasonic method. The effect of Et-OH on the dispersion of bentonite clay at various mixing temperatures in case of different type of rubber matrix, i.e., natural rubber (NR), epoxidized natural rubber (ENR25, ENR50) on dynamic mechanical rheology, Payne effect, XRD and mechanical properties of rubber composites were studied in detail. The bentonite clay dispersion in Et-OH at a mixing temperature of 80 °C improves the intercalation and exfoliation in rubber chains. Bentonite clay is highly intercalated in ENR 50-Clay composite, which can be confirmed from its superior mechanical properties. The results indicated that sonication of bentonite clay in Et-OH improves the interlayer spacing of bentonite clay by partial intercalation of rubber matrix.

Particle size-related vertical redistribution of phosphorus (P)-inactivating materials induced by resuspension shaped P immobilization in lake sediment profile

Lake geoengineering with phosphorus (P)-inactivating materials to reduce sediment P loading is often used for eutrophication control. The redistribution of materials in sediment, especially those induced by resuspension, is reportedly a common phenomenon during practical applications, which may interfere with the pollution control. Notably, a recent study by the authors initially found that the heterogeneous properties of materials and sediments varied the P immobilization in different sized sediments which exhibited diverse movement characteristics. Therefore, this study hypothesizes a particle size-related vertical redistribution of materials in the sediment profile induced by resuspension, which shapes sediment P immobilization at different depths. Based on two differently sized materials, lanthanum (La)-modified bentonite clay (Phoslock) and drinking water treatment residue (DWTR), this study found a weakened reduction of mobile P and bioavailable P pool by both DWTR and Phoslock in surface sediment after resuspension. As the depth decreased from >12 to surface 0–1 cm, the remaining mobile P increased from 7.11%–10.8% to 11.0%–17.8% of the total P in the sediment with Phoslock and from 1.66%–4.73% to 9.70%–20.7% of the total P in the sediment with DWTR; meanwhile, bioavailable P pool reduction proportions decreased from 48.6%–72.3% to 3.23%–45.1% for Phoslock and from 51.5%–71.4% to 4.94%–25.2% for DWTR. Further analysis verified the hypothesis of this study; importantly, the redistributions of the potential target P (including mobile and bioavailable P) for immobilization were regulated by relatively small sediments (e.g., <8 μm fraction), which tended to become enriched in surface sediment after resuspension, while relatively large materials (e.g., >63 μm fraction) regulated their redistributions and were more likely to be buried at the bottom of the sediments. Accordingly, to design appropriate strategies for lake geoengineering, relatively small materials (e.g., <8 μm) targeting to immobilize both mobile and bioavailable P are typically recommended to be developed for restoration of lakes with frequent sediment resuspension.

Curcumin functionalized TiO2 modified bentonite clay nanostructure for colorimetric Aflatoxin B1 detection in peanut and corn

This work reports an analytical technique to determine Aflatoxin B1 (AFB1) in food samples using electrostatic interaction with curcumin (Cur) functionalized TiO2 NPs supported on layered structured bentoniteclay(Ti(Cur)O2Bent). TiO2Bent synthesized by thermal decomposition method, obtained crystallite size of 32.4 nm by XRD and SEM uniform morphology of TiO2NPs on the bentonite surface. The optical band gap decreased with intercalation of TiO2 NPs in the interlayers of bentonite than bare TiO2 NPs and showed presence of alumina-silicate in composite by FT-IR for improved ion-exchange properties. Cur form a chelated complex with TiO2Bent due to extended conjugation of the dye at 1,3 diketone moiety as shown by C13 NMR studies. TiO2Bent improved Cur capability to form electrostatic bond with unsaturated aldehyde electrophiles of AFB1 at pH 9.54. This was evidenced by FT-IR at 1647 cm−1 and sp. hybridization by C13 NMR studies for CO bond in AFs. The hypsochromic modification in color of the dye from red (505 nm) to yellow (403 nm) was recorded by UV–Vis in AFB1 spiked peanut (1–5 ppb) and corn (1–20 ppb). Absorption at maximum intensity of ~434 nm in the linear concentration of AFB1 obtained limit of detection (LOD) (3σ) as 1.4 ppb and 0.38 ppb for peanut and corn respectively. Hence, this rapid sensing developed by the green chemicals synthesis of NPs reagent could be developed into paper-based sensor for onsite detection of AFB1 in food sector.

Optimization of Fluoride Adsorption on Acid Modified Bentonite Clay Using Fixed-Bed Column by Response Surface Method.

Using small-scale batch tests, various researchers investigated the adsorptive removal of fluoride using low-cost clay minerals, such as Bentonite. In this study, Column adsorption studies were used to investigate the removal of fluoride from aqueous solution using acid-treated Bentonite (ATB). The effects of initial fluoride concentration, flow rates, and bed depth on fluoride removal efficiency (R) and adsorption capability (qe) in continuous settings were investigated, and the optimal operating condition was determined using central composite design (CCD). The model’s suitability was determined by examining the relationship between experimental and expected response values. The analysis of variance was used to determine the importance of independent variables and their interactions. The optimal values were determined as the initial concentration of 5.51 mg/L, volumetric flow rate of 17.2 mL/min and adsorbent packed-bed depth of 8.88 cm, with % removal of 100, adsorptive capacity of 2.46 mg/g and desirability of 1.0. This output reveals that an acid activation of Bentonite has made the adsorbent successful for field application.

Resuspension and settlement characteristics of lake sediments amended by phosphorus inactivating materials: Implications for environmental remediation

The classical lake internal phosphorus (P) pollution control using P-inactivating materials is typically carried out by reducing the release of soluble P from sediments to overlying water; however, particulate P loading through sediment resuspension could also cause internal P pollution for algae breeding. Therefore, based on lanthanum modified bentonite clay (Phoslock®) and drinking water treatment residues (DWTR), the effect of P inactivating materials on sediment resuspension and settlement were comprehensively investigated to assess the variations in particulate P pollution from sediment. Results showed that both materials could effectively control soluble P pollution from sediment, while both had limited effect on the supplement of particulate P to overlying water. The reason may be that hydrodynamic disturbance was the key factor regulating sediment resuspension and settlement. The disturbance induced the resuspension of different sized sediments, especially <8 μm fractions, while increasing disturbing intensities promoted resuspension of relatively larger sized sediments (e.g., <63 μm). Further analysis suggested that after resuspension and settlement, the efficiencies of reducing bioavailable P by Phoslock® in relatively large sized sediment fraction (e.g., <63 μm) were substantially less than those in relatively small sized sediment (<8 μm). Although the reducing efficacies of DWTR had limited changes in different sized sediments, the remaining bioavailable P were clearly higher in smaller sized sediments with DWTR. The different performances on bioavailable P reduction mainly resulted from the distributions of materials and original P in different sized sediments. These findings indicated the potential supplement of particulate P for algal growth during resuspension and settlement of sediments amended by P inactivating materials. Overall, understanding the sediment P bioavailability and hydraulic properties at different sizes and the lake hydrodynamic conditions is essential to develop appropriate methods to control lake internal P pollution.

HTDMA-modified bentonite clay for effective removal of Pb(II) from aqueous solution

This work studies the Pb(II) removal onto bentonite clay modified by hexadecyl trimethyl ammonium bromide (HDTMA). Characterizations of the unmodified and modified materials were performed by using XRD, SEM, TG-DSC, FT-IR, and BET surface area analyses. Factors influencing the uptake of Pb(II) from aqueous solution, such as pHsolution, ion strength, uptake time, adsorbent dosage, and initial Pb(II) concentration, were examined. The obtained results showed that bentonite clay was successfully modified by HDTMA, resulting in an increase in its surface area by about 70 %. The Pb(II) adsorption onto modified bentonite clay reached equilibrium at pH = 5.0 after 120 min. Studies within the isotherm and kinetic models demonstrated that the adsorption followed the Sips isotherm and pseudo-second-order kinetic models. The maximum monolayer adsorption capacity calculated from the Langmuir model at 30 °C was 25.8 mg/g, which is much higher than that obtained for the unmodified sample (18.9 mg/g). The FT-IR and TG-DSC analyses indicated that the formation of inner-sphere complexes plays a fundamental role in the mechanism of Pb(II) uptake onto HDTMA-bentonite clay. This mechanism of Pb(II) adsorption was further investigated, for the first time, by using the positron annihilation lifetime (PAL) and electron momentum (EMD) measurements. The PAL and EMD analyses indicated that the existence of Al and Si mono-vacancies in the HDTMA-bentonite should have essential contributions to the adsorption mechanism. In particular, we found a very interesting mechanism that the Pb(II) adsorption should occur inside the interlayer spaces of the HDTMA-bentonite.

Engineering TiO2 supported CTAB modified bentonite for treatment of refinery wastewater through simultaneous photocatalytic oxidation and adsorption

This study reports the removal of hydrocarbon pollutants from petroleum refinery wastewater by simultaneous photo-catalytic oxidation and adsorption using TiO2 loaded on Cetyl-trimethyl Ammonium bromide modified Bentonite clay (TiO2/CTAB-Bt). The synthesized CTAB-Bt and hybrid TiO2/CTAB-Bt were characterized by XRD, SEM, EDX, and FTIR techniques. The adsorption efficiency of CTAB-Bt was investigated using model refinery wastewater containing phenol, benzene, toluene, and naphthalene (100 ppm each). Under the optimum conditions of 0.8 g/100 mL CTAB-Bt adsorbent dosage, 40 °C, and 120 min contact time, maximum adsorption of hydrocarbons (94%) was attained. The adsorption followed pseudo-first-order kinetics and best fitted with the Langmuir isotherm model. Enthalpy (ΔH°), Gibbs free energy (ΔG°) and entropy (ΔS°) data of the system revealed that the adsorption process was endothermic, spontaneous and feasible. Through simultaneous photocatalytic oxidation under UV light irradiation and adsorption using TiO2/CTAB-Bt, the maximum removal (93%) of hydrocarbons from the model wastewater was achieved under milder conditions of 1100 mg/500 mL of TiO2/CTAB-Bt, 30 °C temperature and 60 min contact time. In the case of real refinery wastewater, CTAB-Bt realized 92% decrease in the COD via adsorption at 40 °C in 120 min, while simultaneous photocatalytic oxidation and adsorption achieved 94% decrease in COD at 30 °C in 60 min. The reaction products of photocatalytic oxidation of refinery wastewater were analyzed by GC–MS analysis. This study reports a new and interesting strategy of photocatalytic oxidation and adsorption for the remediation of hydrocarbon pollutants from refinery wastewater using CTAB-Bt.

Evaluation of bentonite clay in modified and unmodified forms to remove fluoride from water.

The feasibility of fluoride adsorption from aqueous solutions using naturally available bentonite clay in both modified and unmodified forms is investigated in this report. Scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy analysis was applied to describe the structure and nature of modified and unmodified bentonite clay. The physicochemical characteristics of the adsorbent were also investigated for moisture content, pH, apparent density, specific surface area, cation exchange capacity and its point-of-zero charge. SEM images reveal particles are dispersed homogeneously and are irregular in shape. XRD and EDX analyses reveal that the bentonite is composed of seven materials: calcite, silica, alumina, hematite, bornite and green cinnabar, and chloride which are considered as impurities. Raw bentonite clays have shown very low fluoride removal efficiency (47.19%). Modification of the clay surface with HCl and aluminum oxide, on the other hand, increased fluoride removal efficiency to 79.77% and 94.38%, respectively. At 5 mg/L initial fluoride concentration, 10 cm bed depth packed dose of adsorbent, and 180 min breakthrough time, a 2.88 mg/g of fluoride removal capacity was observed. As a result, aluminum oxide modified bentonite clay was chosen for further investigation and the results are not presented here.

Adsorption of propranolol hydrochloride from aqueous solutions onto thermally treated bentonite clay: A complete batch system evaluation

Sustainability is an increasingly prominent issue in our modern society. Propranolol, a β-blocker mainly indicated for the control of hypertension, is an emerging contaminant that has already been reported as non-biodegradable, highly persistent, partially removed by the conventional treatment processes of water and wastewater and harmful to aquatic organisms. The removal of propranolol hydrochloride by batch adsorption using calcined Verde-lodo, a thermally modified bentonite clay, was assessed in this work. pH analysis indicated that natural pH could be used in the experiments. The kinetic study, conducted at 25 °C and deeply evaluated by rate laws and mass transfer models, achieved the equilibrium after 15 h, with pseudo-second order model showing the best fit and resistance to mass transfer in external film as the limiting step of adsorption. The isotherms’ study, conducted at 20, 30 and 40 °C, showed a maximum adsorptive capacity of 0.468 mmol.g−1. The thermodynamic analysis revealed a spontaneous, endothermic and entropy-governed adsorptive process (with increase in randomness and disorder level at the solid/liquid interface), and that clay surface is energetically heterogeneous. The energies of the electron-rich and electron-deficient sites, as well as the quantum chemical parameters (based on DFT theory), were determined for propranolol. The effects of molecular sieving could be ignored. Experimental data was supported by characterization results of the clay before and after adsorption, which indicated that the process modified its surface by the effective removal of the drug from aqueous solutions.

Influence of organoclay dispersion on air retention and fatigue resistance of tyre inner liner compound

AbstractIn a pneumatic tire, the contained air carries the load of the vehicle and also augments performance for other functional requirements, such as, rolling resistance, ride and handling, durability, and so on. The inner liner of the tire is responsible to ensure air retention by virtue of its high air impermeability. The present study focused on developing inner‐liner compounds of improved air impermeability by utilizing platelet filler (layered silicate). The obtained organoclay was subjected to a pre‐treatment process called exfoliation to increase the d spacing between the clay layers that further improved the morphological aspect of the compound. The inner‐liner compound has been modified by partial replacement of carbon black with organically modified bentonite clay in 1:1 and 2.5:1 ratio. Air impermeability of rubber compounds was tested in a gas permeability tester. Field emission scanning electron microscope, transmission electron microscope, atomic force microscope, and x‐ray diffraction were utilized to understand the distribution and dispersion of clay in the rubber compounds. Fatigue crack growth analysis was carried out to measure the fatigue life of the materials. The modified compounds exhibited air impermeability improvement from 7% to 30% vs the reference carbon‐black filled compound with improved mechanical properties and filler dispersion.

Adsorption of ciprofloxacin onto thermally modified bentonite clay: Experimental design, characterization, and adsorbent regeneration

Ciprofloxacin (CIP) is the most prescribed antibiotic worldwide and is considered an emerging contaminant. The adsorption of ciprofloxacin onto calcined Verde-lodo (CVL) bentonite clay in a static system was evaluated in this study. CVL clay was characterized by Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Thermogravimetric Analysis, and Zeta analyzer before and after application to examine the adsorption mechanism. Statistical techniques of experimental design were used to determine the best conditions to maximize the adsorption capacity of CIP. Static system tests were performed to evaluate the kinetics, isotherm, and thermodynamics of adsorption. The system reached a maximum Langmuir removal capacity (25 °C) of 114.4 mg g−1 and CVL clay displayed considerable reuse capacity with heat treatment at 500 °C. The ability for regeneration and high removal capacity of CVL provides a promising strategy to mitigate emerging contaminants present in wastewater.

The Benefits of the ZnO/Clay Composite Formation as a Promising Antifungal Coating for Paint Applications

The presence of mold is a serious problem in different environments as industrial, agricultural, hospital and household, especially for human health. Large quantities of mold spores can potentially cause allergic reactions and respiratory problems. Therefore, it is essential to keep buildings free of fungi without harming human health and the environment. Here, we pose a composite of modified bentonite clay and ZnO nanoparticles as an alternative antifungal preservative. The new composite is obtained by an easy and eco-friendly method based on a dry nanodispersion, without altering the properties of each material. The antifungal test reveals a robust response against fungi thanks to the ZnO nanoparticles’ contribution. Our results reveal that the antifungal activity of ZnO/clay composite is governed by both a uniform distribution and an adequate concentration of the ZnO nanoparticles onto the clay surface. Specifically, we find that for concentration below 10 wt.% of the ZnO nanoparticles, the nanoparticles are well dispersed onto clay giving rise to an excellent antifungal response. By contrast, when the concentration of ZnO increases, the formation of ZnO agglomerates onto the clay surface is favored. This effect provokes that antifungal behavior changes towards a more moderate improvement. Finally, we have demonstrated that this composite can be used as a promising paint preservative for antifungal applications.

Effect of halloysite nanotubes and organically modified bentonite clay hybrid filler system on the properties of natural rubber

The versatility and potential have framed natural rubber (NR) nanocomposites as the focal point in the polymer research field and industry. Currently, NR nanocomposites filled with hybrid nanostructures is an interesting area than single filler or conventional filler systems. Halloysite nanotube (HNT) and bentonite clay are well-studied potential fillers of polymers. This work is an attempt to study the effect of hybrid filler system of HNT and organically modified bentonite nanoclay (NC) in the properties of NR. NR/HNT-NC systems with varied filler concentrations were prepared in a two-roll mixing mill. Properties such as cure characteristics, morphology, mechanical, thermal, and transport behavior were analyzed in detail. The prepared composites had better wear properties than gum vulcanizates. Improvement in physical properties was observed due to the increased contact surface area between the filler and the matrix. The nanocomposite with 2 wt% hybrid filler shows a 31% decrease in abrasion loss compared to neat NR composite. Apparently, 4 wt% of hybrid filler could improve modulus at 300% strain and tear by approximately 57% and 14%, respectively. The ability to withstand high strain was evident from the improved crack growth resistance as observed in micrographs. Lorenz–Park plots were employed to analyze the rubber–filler interaction. The activation energy of thermal degradation was calculated using Coats–Redfern equation.
