摘　　要：随着抗生素的普遍应用,抗生素的水体污染问题也越来越严重。目前,从水中去除抗生素污染物技术包括物理吸附、絮凝和化学氧化。然而,这些过程通常会在水中留下大量的化学试剂和难以处理的沉积物,导致后处理比较困难。光催化技术是利用光催化材料,在光照的情况下使抗生素彻底分解,最终形成无毒的CO_(2)和H_(2)O。光催化降解抗生素具有成本低、效率高、无二次污染的优点。本文综述了几种常用的降解抗生素的光催化材料的研究进展,并对其今后的研究与应用作了进一步展望。With the widespread use of antibiotics,the problem of water pollution caused by antibiotics is becoming increasingly serious.Currently,technologies for removing antibiotic pollutants from water include physical adsorption,flocculation,and chemical oxidation.However,these processes often leave a large amount of chemical reagents and difficult-to-dispose sediment in water,making post-treatment more difficult.Photocatalytic technology uses photocatalytic materials to decompose antibiotics under light,ultimately forming non-toxic CO_(2) and H_(2)O.Photocatalytic degradation of antibiotics has the advantages of low cost,high efficiency and free secondary pollution.In this paper,the research progress of several commonly used photocatalytic materials for degrading antibiotics is reviewed,and their future researches and applications are also prospected.
