Various pharmaceuticals have been detected in natural water and wastewater bodies, causing threats to water ecosystem and human health. Although electrochemical anodic-oxidation (EAO) has been shown to be efficient for pharmaceuticals degradation from aqueous solution, it still has a distinct need to apply EAO technology for pharmaceuticals removal rationally. This review provides the most recent progress on the mechanisms, influencing factors, and new technique of EAO for pharmaceuticals degradation. The mechanism and superiority of EAO were analyzed. Major influencing factors (e.g., electrode materials, electrochemical reactor, applied current density, anode-cathode distance, electrolyte type and concentration, initial solution pH value, and initial pharmaceuticals concentration) were discussed on the removal of pharmaceuticals. The latest development of reactive electrochemical membranes (REM) was regarded as an emerging EAO technique, and it was also highlighted. This work revealed that the EAO of pharmaceuticals has extraordinary application prospects in the field of water and wastewater treatment.
各种药品已在天然水和废水体中被检测到，对水生态系统和人类健康构成威胁。尽管电化学阳极氧化（EAO）已被证明可有效降解水溶液中的药物，但仍需要合理地应用 EAO 技术来去除药物。本综述提供了 EAO 降解药物的最新机制、影响因素和新技术方面的进展。分析了 EAO 的机制和优势。讨论了影响药物去除的主要因素（如电极材料、电化学反应器、施加电流密度、阴阳极距离、电解质类型和浓度、初始溶液 pH 值和初始药物浓度）。将反应电化学膜（REM）的最新发展视为一种新兴的 EAO 技术，并对其进行了强调。这项工作表明，药物的 EAO 在水和废水处理领域具有非凡的应用前景。
