摘　　要：锰是环境中广泛存在的过渡金属元素,其价态丰富,性质活跃,广泛参与污染物的环境地球化学过程,并在污染治理修复中发挥重要作用。三价锰(Mn(Ⅲ))作为一种中间价态锰,因存在时间短,易歧化,导致其在各种涉锰反应中的作用长期被忽视。近年来,越来越多的研究证实了Mn(Ⅲ)在污染物迁移转化过程中发挥重要作用。文章阐述了Mn(Ⅲ)的重要理化性质,梳理了其在重金属、非金属等无机污染物、有机污染物转化及生物系统中的重要作用,总结了氧化、还原、催化等作用机制,分析了其在污染去除应用中的优点和不足,为Mn(Ⅲ)相关基础研究和实际应用提出可能的方向。Manganese is a transition metal element widely existing in the environment.Its valence state is rich and its proper⁃ties are active.It is widely involved in the environmental geochemical process of pollutants,and its role in pollution treatment and remediation has been widely studied.Trivalent manganese(Mn(Ⅲ)),as a kind of intermediate valence manganese,is easy to disproportionate due to its short existence time,leading to its long-term neglect of its role in the oxidation-reduction reaction.In recent years,more and more studies have confirmed the important contribution of Mn(Ⅲ)in the process of interac⁃tion between multiple manganese-containing systems and environmental pollutants.This paper describes the basic physical and chemical properties of Mn(Ⅲ),and sorts out its important role in the transformation of heavy metals,non-metals and other inorganic pollutants,organic pollutants,and biological systems.The mechanism of oxidation,reduction,and catalysis of Mn(Ⅲ)is summarized,and its advantages and disadvantages in the application of pollution removal are analyzed,and possible directions for the related basic and application research of Mn(Ⅲ)are proposed.
