摘要/Abstract

摘要：

水体中的有毒重金属对人类健康和生态环境的危害巨大,而这些重金属通常又是重要的自然资源。如何将他们从污染的水体中分离并回收再利用,是当前环境保护领域的研究热点之一。选择性吸附是根据重金属的特性,制备相应的吸附材料或者设置一定的溶液条件使重金属离子从废水中分离出来。综述了近年来有关选择性吸附水体重金属的研究进展,并根据吸附原理进行了分类。重点阐述了针对汞、铜、铅和铬的选择性吸附及其原理,并对该类研究进行了展望。

关键词: 重金属污染, 水处理, 选择性吸附

Abstract:

Toxic heavy metals in water have been a serious hazard to human beings health and eco-environment.However,these heavy metals are usually important natural resources. How to separate them from polluted water body and reuse them is a hot issue in environmental protection field. Selective adsorption is to prepare corresponding adsorbing materials or set certain solution conditions，according to the characteristics of heavy metals，so as to separate heavy metal ions from wastewater. Research progress in selective adsorption of heavy metals in recent years is summarized and classified based on adsorptive principles. The selective adsorption of Hg，Cu，Pb and Cr and their principles are expounded emphatically. In addition , the research on selective adsorption is predicted.

Key words: heavy metals pollutant, water treatment, selective adsorption
