摘　　要：砷污染是全世界突出的环境问题,对污染水中砷的吸附处理受到广泛关注.施氏矿物凭借其优异的吸附性能与简便经济的制备方法,被认为是一种具有重大潜力的除砷材料.本文概述了施氏矿物的发现及其矿物学特征,重点介绍了施氏矿物对砷的去除效果及其影响因素,并分析了施氏矿物的除砷机理及砷的再释放性,同时对施氏矿物的应用研究进行了总结,最后提出了施氏矿物除砷研究中存在的问题及展望.Arsenic pollution is a serious environmental problem all over the world and the adsorption treatment of arsenic in contaminated water has attracted wide attention. Because of its excellent adsorption property and simple and economical preparation method, schwertmannite was considered as an arsenic removal material with great potential. In this paper, a review was presented on the discovery and mineralogical characteristics of schwertmannite as well as the removal effect and influencing factors of arsenic by schwertmannite. The mechanism of arsenic removal and arsenic rerelease of schwetmannite were analyzed and the application research of schwertmannite was summarized. At last, the problems and prospects in the study of arsenic removal were put forward.
