改性蒙脱石修复除草剂污染环境的研究

Use of Modified Montomorillonite for Environment Contaminated with Herbicides

近年来,在农业生产中广泛使用的除草剂已成为生态环境的一个主要污染源,这已引起了人们的高度重视。通过对天然蒙脱石进行表面有机改性而制得的改性蒙脱石被认为可以用来减缓除草剂在土壤中的释放、减小其对环境造成的污染。利用改性蒙脱石修复受污染环境的技术得到了广泛关注。本文简述了除草剂对环境污染的现状,介绍了蒙脱石的基本特征及蒙脱石有机改性剂的种类,阐述了国内外近年来利用有机改性蒙脱石修复除草剂污染水体和土壤的研究进展,并提出了改性蒙脱石修复有机物污染环境未来的研究方向。

In recently years, the use of herbicides in agriculture has become a main source of pollution of environment,which has attached great importance to people. Modified montomorillonite,which could been prepared by modifying natural montomorillonite with some organics,has been proposed to enhace the retention of herbicides in soil and reduce the risk of environment contamination. Use of modified montomorillonite as a amendment for remediation of contaminated environment has attrached considerable attention. The current environment pollution situation caused by hercide,the basic characteristics of montmorillonite,the species of montmorillonite organic modifier,and the research progress of use of modified montomorillonite for environment contaminated with herbicides at home and abroad in recent years were discussed. The further research directions were prospected in this research field.
