摘要：

To address the issues of electrode passivation and high electric energy consumption ( EEC ) associated with the removal of antibiotic wastewater using traditional direct current electrocatalytic oxidation (DCEO) with Boron-Doped Diamond (BDD) electrodes, this study aims to develop an efficient, low-cost, and self-cleaning BDD electrode pulsed alternating electrocatalytic oxidation (BDD-PAEO) technology. The experimental findings demonstrated that, under optimal conditions, the BDD-PAEO mode achieved a 99.9% removal efficiency for sulfamethazine...
