Global consumption and discharge of antibiotics have led to the rapid development and spread of bacterial antibiotic resistance. Electrochemical advanced oxidation processes (EAOPs) are becoming popular for treating water/wastewater containing antibiotics due to their high efficiency and ease of operation. This review summarizes various forms of EAOPs for antibiotic degradation, assesses their performance, discusses key factors influencing the degradation process, reviews degradation mechanisms and pathways, and highlights challenges and research needs for the application of EAOPs in antibiotic treatment.
Global consumption and discharge of antibiotics have led to the rapid development and spread of bacterial antibiotic resistance. Among treatment strategies, electrochemical advanced oxidation processes (EAOPs) arc gaining popularity for treating water/wastewater containing antibiotics due to their high efficiency and easiness of operation. In this review, we summarize various forms of EAOPs that contribute to antibiotic degradation, including common electro-chemical oxidation (EO), electrolyte enhanced EO, electro-Fenton (EF) processes, EF-like process, and EAOPs coupling with other processes. Then we assess the performance of various EAOPs in antibiotic degradation and discuss the influence of key factors, including electrode, initial concentration and type of antibiotic, operation conditions, electrolyte, and water quality. We also review mechanisms and degradation pathways of various antibiotics degradation by EAOPs, and address the species and toxicity of intermediates produced during antibiotics treatment. Finally, we highlight challenges and critical research needs to facilitate the application of EAOPs in antibiotic treatment.
