摘　　要：环境水体中检测到大量药物的存在,主要包括抗生素,抗惊厥抗抑郁药物,解热和非甾体消炎药,血脂调整剂,β-阻滞剂等。传统的水处理技术并不能有效地去除这些药物,存在于水体中的环境药物对公共健康的潜在危害引起了广泛的关注。文中简要地介绍了近年来光催化技术在降解环境药物动力学和机理方面的研究进展,试图找出水体中环境药物降解的一般规律,为环境水体中该类物质的迁移和转化提供理论依据。A vast number of pharmaceuticals have been detected in aquatic environment,including antibiotic,anticonvulsants and anti-anxiety agents,antipyretics and non-steroidal anti-inflammatory,blood lipid regulator,beta-blocker,and so on.This indicates their ineffective removal from water and wastewater using conventional treatment technologies.Concerns have been raised over the potential adverse effects of pharmaceuticals on public health and their persistent in aquatic environment.In order to probe the general laws of photocatalytic degradation and then provide a theoretical foundation to deal with aquatic pharmaceuticals,the process of kinetics and mechanisms on photocatalytic degradation of aquatic pharmaceuticals are reviewed in recent years.
