微孔材料在水处理中吸附持久性有机污染物的研究进展

Research Progress of Microporous Materials Adsorbing Persistent Organic Pollutants in Water Treatment

持久性有机污染物(POPs)是指具有持久性、生物累积性和高毒性等特点的有机物。近年来POPs的水体残留污染问题十分严峻,对人类健康和环境造成了严重危害。对于环境介质中大多数的POPs,目前主要采用吸附法进行去除和降解。基于此,阐述和总结了石墨烯、碳纳米管和沸石3种典型的微孔吸附剂在水处理中去除POPs的最新进展,并为当下开发一种新型、高效且环保的吸附材料去除环境中POPs的研究提供了一些建议和新的思路。

Persistent Organic Pollutants(POPs)refer to organic matters with the characteristics of persistence,bioaccumulation,and high toxicity.In recent years,the problem of POPs residual pollution in water bodies has become very serious,which poses a certain risk to human life and health.For most POPs in environmental media,biochemical methods,especially adsorption methods,are mainly used for removal and degradation.This paper describes and summarizes the latest progress in the removal of POPs in water treatment by three typical microporous adsorbents of graphene,carbon nanotubes and zeolite,and develops a new,efficient and environmentally friendly adsorbent for the removal of POPs in the environment.The research provides some suggestions and new ideas.
