光催化降解水体中磺胺类抗生素的研究进展

磺胺类抗生素（SAs）的滥用和施用废水的任意排放导致水体中抗生素污染问题日益严重,而光催化是目前最有前途的处理方法之一。本文综述了光催化降解水体中SAs的机理和研究进展,其中着重介绍了TiO₂改性材料和石墨相氮化碳（g-C₃N₄）基材料作为光催化剂降解SAs;分析了当前的研究趋势,并指出了现存的主要问题,为光催化降解水体中SAs技术的进一步发展和光催化材料的改性提供借鉴。

Recent developments in photocatalytic degradation of sulfonamide antibiotics in water

The abuse of sulfanilamide antibiotics （SAs） and the arbitrary discharge of wastewater lead to the increasing problems of antibiotic pollution in water. Photocatalysis is one of the most promising treatment methods. In this paper,the mechanism and research progress of photocatalytic degradation of SAs in water are reviewed,with emphasis on photocatalytic degradation of SAs by using TiO₂ modified materials and graphitic carbon nitride （g-C₃N₄） based materials as photocalalyst. The current research trend is analyzed and the main problems are pointed out,which provides reference for further development of photocatalytic degradation of SAs in water and modification of photocatalytic materials.
