凹凸棒石对重金属离子吸附行为研究现状

Research Status of the Attapulgite Adsorption of Heavy Metal Ion

凹凸棒石是一种晶质水合镁铝硅酸盐矿物,对重金属离子具有良好的吸附作用。文章简述了凹凸棒石在重金属离子吸附性能研究方面的现状、凹凸棒石改性和吸附机理研究的方法。

Attapulgite is a kind of hydrated magnesium-aluminium crystalline silicates, which has the efficient adsorption ability of heavy metal ion. The paper gave a brief introduction of the research status of the attapulgite adsorption of heavy metal ion, the study of surface modification of attapulgite and the adsorption mechanism for Attapulgite.
