This study investigates the photooxidation of Roxithromycin and Erythromycin, two prevalent antibiotics found in antibiotic industry wastewater, utilizing a CeO₂/ZnO nanocomposite as a photocatalyst. The synthesized CeO₂/ZnO nanocomposite exhibits enhanced photocatalytic activity under sun light irradiation, promoting the degradation of these antibiotics. Various parameters, including catalyst loading, initial antibiotic concentration, and reaction time, were systematically optimized to assess their influence on the photocatalytic efficiency. The results indicate significant degradation rates for both antibiotics. These findings underscore the potential of CeO₂/ZnO nanocomposites as a viable solution for the remediation of antibiotic-contaminated wastewater, contributing to environmental sustainability and public health protection.
