摘要
随着我国对水污染治理力度的加大,对高性能水处理材料的需求也越来越迫切。以凹凸棒石为代表的黏土矿物因其储量大、价格低廉、对多种污染物吸附好以及环境相容性好等特点受到广泛关注。本文综述了近年来凹凸棒石基水处理新型吸附材料的研究进展,主要包括利用凹凸棒石一维纳米棒晶表面改性、负载和复合等新型吸附材料。重点介绍了各种新型吸附剂的构筑方法及其研究进展,展望了未来凹凸棒石基新型吸附剂的研发方向。
Recently,the demand for the high-performance adsorbent increases continuously with the greater efforts of treatment water pollution in China.The clay mineral which is represented with the attapulgite has attracted much attention due to the vast reserves,low cost and the excellent adsorption performance for varies pollutants and good environmental compatibility.In this paper,the research process of novel adsorbent for water treatment based on attapulgite were reviewed,which containing the surface modification or surface supporting of the one dimensional nanorods and the composites adsorbent.The preparation method and the research progress have been summarized mainly,and the research direction of novel adsorbent based on attapulgite has been expected.
