Cefoperazone is a widely utilized antibiotic from the cephalosporins group to treat bacterial infections. Nevertheless, due to its extensive use as a β-lactam antibiotic, it has been found to accumulate in aquatic environments, leading to notable adverse effects on flora and fauna. Consequently, there arises a necessity for its removal from the environment. The aim of this work was to investigate the efficiency of photocatalytic degradation of cefoperazone by ZnO and H2O2 using different types of radiation (simulated solar (SS), UV-LED, and UV). The applied nanomaterial in the presence of H2O2 showed significant effi- ciency in removing cefoperazone compared to direct photolysis. In the first 20 min of irradiation, 49.0% and 59.4% of cefoperazone were degraded when SS and UV-LED were used, respectively, while cefopera- zone was completely degraded under UV irradiation. The reaction rate constant indicates that the degrada- tion of cefoperazone is pseudo-first order..
