Özet
In this study the oxidation of Bisphenol-A (BPA) was investigated using heterogeneous photo-Fenton-like oxidation under visible light irradiation over iron containing TiO2 catalysts. The catalysts were prepared by the incipient wetness impregnation method with different iron contents (1 and 5 wt%) and characterized by XRD, SEM, FT-IR, nitrogen adsorption, UV-Vis DRS, and ICP-AES measurements. Among the prepared catalysts the 1 wt% iron containing the TiO2 catalyst showed better catalytic activity (with a chemical oxygen demand (COD) reduction of 65.4% at the end of 6h of oxidation) than the other catalysts. The effects of the parameters such as the initial BPA concentration, H2O2 amount, catalyst amount, the pH of the initial BPA solution, and reaction temperature were studied with that catalyst on the heterogeneous photo-Fenton-like oxidation of an aqueous BPA solution. The small amount of iron that leached to the solution and the reusability of the catalyst illustrates that the process is mainly the heterogeneous photo-Fenton-like process, instead of the homogeneous photo-Fenton-like process. The degradation of BPA was described by the first order kinetics with an activation energy of 22.5 kJ/Mol.
