层状双金属氢氧化物在水处理中的应用

Application of layered double hydroxides in water treatment

日趋加剧的水污染已对人类的生存安全构成重大威胁,成为人类健康、经济和社会可持续发展的重大障碍,因此,如何快速有效地处理污染的水资源是人们一直不断探索的课题。层状双金属强氧化物具有大的比表面积、可调节的阳离子特性,均匀分散的阳离子,所以常被用来直接吸附水中的污染物或者作为催化剂用于水处理。本文概述了层状双金属氢氧化物的合成方法以及在水处理中的应用,并对其在未来的发展趋势进行了展望。

The increasing water pollution has posed a great threat to the survival and safety of human beings,and become a major obstacle to the sustainable development of human health,economy and society.Therefore,how to deal with polluted water resources quickly and effectively is a subject that people have been constantly exploring.Layered bimetallic strong oxides with large specific surface area,adjustable cationic characteristics and uniformly dispersed cations are often used to adsorb pollutants directly in water or as catalysts for water treatment.In this paper,the synthesis method of layered bimetallic hydroxide and its application in water treatment are summarized,and the development trend of layered bimetallic hydroxide in the future is prospected.
