水环境中六六六和汞的富集分离

Progress in Enrichment and Separation of HCH and Mercury in Water System

污染物富集分离是环境样品前处理过程中的关键环节,对污染物分析监测的准确性和灵敏性至关重要。目前,有效的富集分离仍然是环境分析的瓶颈问题。本文以水中典型的有机污染物六六六和无机污染物汞为对象,结合近期最新的研究报道,概述了水体环境中六六六和汞富集分离的研究新进展,就环境纳米材料在富集分离过程中的应用提出了存在的问题,并对其发展前景进行了展望。

Efficient enrichment and separation of pollutants are the key technologies for sample pretreatment,but usually the bottle-neck steps due to the complex of environmental samples and extremely low concentrations of pollutants.In this review,we introduce the recent and important progress regarding the developed materials for the enrichment and separation of representative aqueous contaminants:HCH and mercury.In addition,the existing problems of these environmental nanomaterials for enriching and separating pollutants are proposed.The future challenges of environmental nanomaterials are discussed as well.
