摘要
基于砷是一种自然界普遍存在的有毒元素,砷污染已成为一个亟待解决的全球性的环境问题。围绕低分子类铁盐、高分子类铁盐及其它铁类化合物三个方面综述了当前铁盐除砷技术的研究进展。结果表明:(1)铁盐除砷技术具有除砷效果好、经济、操作简单等优点;(2)研制高效、价成本、低能耗的除砷铁盐药剂以及多种药剂的联合使用将成为今后铁盐除砷技术的发展方向。
Arsenic is a prevalent toxic element in nature and the treatment of water with arsenic pollution has become a global environmental problem.The study introduces the technology of arsenic removal by ferric salt from the aspects of low molecular ferric salts,high molecular ferric salts and other iron species.The results show：（1）the technology of arsenic removal by ferric salt has many advantages,such as higher removal efficiency,economy,simple operation and so on;（2）developing the ferric salts with high efficiency,low cost and low energy consumption and combined use of several chemicals will be the development direction of the technology of arsenic removal by ferric salt.
