水体中所含抗生素残留的种类和数量不断增多,污染成分也越来越复杂。传统的微生物水处理技术并不能有效地去除这些药物。光催化氧化技术具有氧化能力强、无二次污染、反应条件温和、分解速度快以及对降解物质具有广普性等优点,广泛应用于抗生素降解。按照金属类光催化剂、非金属类光催化剂和MOFs类光催化剂分类,对光催化降解抗生素类药物的研究进展进行了综述,总结了不同光催化剂的结构特征、性能,并对光催化剂降解抗生素领域的未来发展前景进行了展望。

Varieties and quantity of antibiotic residues in water are increasing,and the pollution components are becoming more and more complex.Traditional microbial water treatment techniques cannot effectively remove these drug residues.Photocatalytic oxidation technology has the advantages of strong oxidation ability,no secondary pollution,mild reaction conditions,fast decomposition rate and wide availability to degradable substances,so it is widely used in antibiotic degradation.Upon the classification of metal photocatalysts,non-metal photocatalysts and MOFs photocatalysts,this paper reviews the research progress on photocatalytic degradation of antibiotics,summarizes the structural characteristics and properties of various photocatalysts,and prospects the future development in the field of photocatalytic degradation of antibiotics.
