“…The highest sorption capacity was obtained for BPB due to its higher log K ow (4.13) comparing to other bisphenols, while the lowest sorption capacity was found in BPS, corresponded to its low log K ow (1.65). It could be explained that the analytes having larger log K ow preferred to leave the aqueous phase, and the hydrophobic interaction was readily driven between hydrophobic site of bisphenols and hydrophobic tail of CTAB on the sorbent [ 36 , 37 , 38 ]. In addition, dipole-dipole interaction possibly occurred from positively charged CTAB species on the sorbent and electron-donating hydroxyl group of bisphenols [ 39 ].…”

“…The ability of the Fe-Al MMH@TiO 2 -CTAB sorbent to adsorb bisphenols (concentration range: 2000-8000 μg L À1 ) was investigated under optimized extraction conditions. The maximum sorption capacity is calculated using equation preferred to leave the aqueous phase, and the hydrophobic interaction was readily driven between hydrophobic site of bisphenols and hydrophobic tail of CTAB on the sorbent [36,37,38]. In addition, dipole-dipole interaction possibly occurred from positively charged CTAB species on the sorbent and electron-donating hydroxyl group of bisphenols [39].…”

In this work, the magnetic sorbents based on different surfactant-coupled titanium dioxide coated iron-aluminium mixed metal hydroxide were investigated as sorbent for extraction of bisphenol compounds. The structure, morphology, and magnetic property of the synthesized sorbents were investigated. The cetyltrimethylammonium bromide-titanium dioxide coated iron-aluminium mixed metal hydroxide (Fe-Al MMH@TiO 2 -CTAB) exhibited excellent extraction performance toward bisphenols and was selected as the sorbent for development of magnetic solid phase extraction (MSPE) method. The entire MSPE process was optimized, and the extract was analyzed by high performance liquid chromatography with photodiode array detector. The method provided wide linear calibration ranges for bisphenols between 0.3-6000 μg L À1 with maximum enrichment factors of 280. The limits of detection and limits of quantification were in the ranges of 0.08-0.3 and 0.3-1.0 μg L À1 , respectively. The proposed MSPE method was tested for determination of bisphenols in carbonated beverages. The studied carbonated beverages were mostly free of bisphenol contamination; however, BPS, BPA and BPB were detected in samples taken from defective cans. The relative recoveries ranging of 80.2-118.9% were obtained. The asprepared Fe-Al MMH@TiO 2 -CTAB sorbent provided high sorption capacities in the range of 2215-2451 mg kg À1 and could be a promising material for bisphenols in beverage samples.

“…The terminal half-life for BPA in the body is about 17.6 ± 7.69 h [10]. Thus, various types of treatment were developed to remove BPA from water in the environment including adsorption, nanofiltration, biological agents and emulsion liquid membrane [11][12][13][14]. However, there are limitations for these technologies, such as fouling for adsorption, nanofiltration is only applicable for certain particle size and not for large particle size and biological agents need long time duration to achieve optimum performance while emulsion liquid membranes have low membrane stability due to emulsification reaction [15][16][17].…”

Bisphenol A Removal Using Visible Light Driven Cu2O/PVDF Photocatalytic Dual Layer Hollow Fiber Membrane

et al. 2022

Bisphenol A (BPA) is amongst the endocrine disrupting compounds (EDCs) that cause illness to humans and in this work was removed using copper (I) oxide (Cu2O) visible light photocatalyst which has a narrow bandgap of 2.2 eV. This was done by embedding Cu2O into polyvinylidene fluoride (PVDF) membranes to generate a Cu2O/PVDF dual layer hollow fiber (DLHF) membrane using a co-extrusion technique. The initial ratio of 0.25 Cu2O/PVDF was used to study variation of the outer dope extrusion flowrate for 3 mL/min, 6 mL/min and 9 mL/min. Subsequently, the best flowrate was used to vary Cu2O/PVDF for 0.25, 0.50 and 0.75 with fixed outer dope extrusion flowrate. Under visible light irradiation, 10 mg/L of BPA was used to assess the membranes performance. The results show that the outer and inner layers of the membrane have finger-like structures, whereas the intermediate section of the membrane has a sponge-like structure. With high porosity up to 63.13%, the membrane is hydrophilic and exhibited high flux up to 13,891 L/m2h. The optimum photocatalytic membrane configuration is 0.50 Cu2O/PVDF DLHF membrane with 6 mL/min outer dope flowrate, which was able to remove 75% of 10 ppm BPA under visible light irradiation without copper leaching into the water sample.

“…BPA is mainly used as a monomer in the production of polycarbonate plastics and epoxy resins [3,4]. Materials containing BPA were extensively used in many products such as thermal paper, food packaging, baby bottles, drink containers, medical devices, and internal coatings in tin cans [5][6][7][8]. Unfortunately, BPA can be gradually released from some of the products mentioned above, under normal conditions of use, into the surrounding environment.…”

Amino-containing polymer-coated magnetite nanoparticles as nano-adsorbents for bisphenol A: Synthesis, kinetic and thermodynamic study

et al. 2022

View full text Add to dashboard Cite

Magnetite nanoparticles coated with poly(dimethyl aminoethyl methacrylate) (PDMAEMA@MNPs) and their quarternized form (PQDMAEMA@MNPs) were successfully synthesized and used as nano-adsorbents for bisphenol A (BPA). The particles were spherical with the average particle size between 10 and 20 nm in diameter with a moderate degree of nanoclustering (ca.150-200 particles/cluster). In terms of adsorption properties, the PDMAEMA@MNPs exhibited a higher BPA adsorption capacity (1.05 mg/g MNP at pH 9) than the quaternized form (0.50 mg/g MNP at pH 9). Equilibrium isotherm, kinetic, and thermodynamic characteristics of BPA adsorption on the PDMAEMA@MNPs were investigated. It was found that the BPA adsorption on the MNPs reached an equilibrium within 5 min and the maximum adsorption capacity (qe) was 9.88 mg/g. The adsorption isotherm study results indicated that the BPA adsorption process on PDMAEMA@MNPs exhibited the best fit with the Freundlich model, and the adsorption kinetics followed the pseudo-second order model with the R2 value of 1.00. The thermodynamic data exhibited a negative enthalpy change (ΔH◦ = -2585.571 J/mol), indicating exothermic BPA adsorption, and a negative Gibbs free energy (ΔG◦), implying a spontaneous BPA adsorption process.
