Abstract
In order to investigate the degradation performance and underlying mechanism of antibiotic pollutants in an acid synergistic system composed of biochar (BC) and oxalic acid (OA) under visible light irradiation, a visible-light-driven BC-OA system (Vis-BC-OA) was established. Degradation experiments were conducted using ofloxacin (OFL) as the model contaminant. The results demonstrated that the system exhibited excellent degradation capability, achieving a high removal efficiency of 98.4% within 100 min. A marked synergistic catalytic effect was observed between BC and OA, whereas efficient degradation was scarcely achieved in single-component systems. Therefore, the Vis-BC-OA system shows promising potential for the removal of antibiotic pollutants.
