Simultaneous adsorption and degradation of bisphenol A on magnetic illite clay composite: Eco-friendly preparation, characterizations, and catalytic mechanism

Abstract Excess bisphenol A (BPA) is a pollutant of concern in different water sources. In this work, magnetic illite clay-composite material (Fe3O4@illite) was synthesized via the coprecipitation method by loading Fe3O4 nanoparticles (nano-Fe3O4) onto surfaces clay. Results from characterizations showed that nano-Fe3O4 embedded into clay nanosheets and existed on clay, thereby reducing degree agglomeration improving dispersibility. The catalytic BPA degradation Fe3O4@illite confirmed superior performance compared with nano-Fe3O4. optimum operating parameters for were 0.3 mL H2O2 at pH 3 presence Fe3O4@illite, which provided maximum capacity up to 816, 364, 113, 68 mg/g epoxy concentration resin wastewater (266 mg/L), synthetic (80 mg/L), Hefei City swan lake (25 mg/L), University (14.94 mg/L), respectively, 180 min reaction time. data conformed pseudo-first-order kinetic model. pathways mineralization study revealed adsorption-Fenton-like principal mechanism demonstrated 100% efficiency even after nine successive runs. regeneration reusability tendency analysis ensured can be easily separated using magnets. Therefore, composite Fenton-like technology promising degradation.
