摘　　要：以土壤/沉积物中普遍存在且具有较强氧化活性的锰氧化物为研究对象,探讨了水-锰氧化物体系对医药品和个人护理用品等典型环境污染物的转化行为,并从污染物的分子结构出发,分别综述了锰氧化物对酚类、胺类、氮杂环、氮杂环N-氧化物、酸类等典型环境污染物的分子转化机制.为该类污染物环境行为及其潜在风险的科学评价、有效控制奠定理论基础.Manganese oxide is one of the natural components in soil/sediment, which would adsorb and transform some organic pollutants due to its high oxidation potential. This paper summarized the transformation mechanisms of organic pollutants by manganese oxide, especially pharmaceuticals and personal care products （PPCPs） containing typical functional groups, e.g. phenol, amine, heterocyclic nitrogen oxides, acids. This summary would provide basic data and theoretical guidance for scientifically evaluating potential environmental risk and controlling pollution for these emerging environmental pollutants in practice.
