摘要
凹凸棒石粘土是一种以凹凸棒石为主要成分的天然非金属粘土矿物,它是一种具有独特层链状结构的晶质水合镁铝硅酸盐矿物,具有比表面积大、化学稳定性好、吸附能力强等特征。作者对国内外有关凹凸棒石粘土的文章进行了综述,详细叙述了凹凸棒石粘土的组成和结构以及相应的改性方法,分类讨论了凹凸棒石粘土在水处理中的应用,分析了我国在研究开发过程中存在的问题,并提出了相应的意见和建议。
Attapulgite clay is a kind of natural nonmetal mineral, which is mainly composed of attapulgite. Attapulgite is crystal hydrated magnesium aluminum silicate with a unique layerchain structure, which gives attapulgite's virtues of high surface area, inert chemical property and excellent adsorptive property. A review of attapulgite clay is presented. The composition, structure and methods of modification are described in detail. Its application to the water treatment is invested. Several problems of research and application of it in China are discussed. Also suggestions and prospects are proposed.
