摘要
水滑石类材料是一类双金属层柱状化合物,因具有特殊的层间离子交换性能和结构记忆效应,在环境污染治理中可作为催化剂、吸附剂和螯合剂,分别用于低温催化还原气态污染物、修复阴离子污染水体和螯合重金属阳离子。针对国内外研究现状,讨论了水滑石类材料在环境污染治理中的应用及最新研究进展。具有螯合性能的水滑石类材料有可能发展为一种新的处理重金属污染的水体净化剂。
Hydrotalcite-like materials are a kind of layered double compounds with widely application. Because they have specific constitution,most of them are applied as catalyzer, sorbent and chelator in the environment, and for low temperature selective catalyticly deoxidizing gassy pollutants, remedying anion polluted water body and chelating heavy metal cations,respectively. The present paper mainly describes latest researches on application of hydrotalcite-like materials in pollution control at home and abroad. The development of a scavenger which has a function of selective uptake of heavy metal ions from an aqueous solution should be enhanced more.
