Description
Summary:A new method for bisphenol A (BPA) degradation in aqueous solution was developed. The characteristics of BPA degradation in a heterogeneous ultraviolet (UV)/Fenton reaction catalyzed by FeCO2O4/TiO2/graphite oxide (GO) were studied. The properties of the synthesized catalysts were characterized using scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometry. FeCO2O4 and TiO2 were grown as spherical shape, rough surface, and relatively uniform on the surface of GO (FeCO2O4/TiO2/GO). Batch tests were conducted to evaluate the effects of the initial pH, FeCO2O4/TiO2/GO dosage, and H2O2 concentration on BPA degradation. In a system with 0.5 g L-1 of FeCO2O4/TiO2/GO and 10 mmol L-1 of H2O2, approximately 90 % of BPA (20 mg L-1) was degraded within 240 min of UV irradiation at pH 6.0. The reused FeCO2O4/TiO2/GO catalyst retained its activity after three cycles, which indicates that it is stable and reusable. The heterogeneous UV/Fenton reaction catalyzed by FeCO2O4/TiO2/GO is a promising advanced oxidation technology for treating wastewater that contains BPA.
