Electromembrane extraction (EME) is a miniaturized extraction technique that has been widely used in recent years for the analysis and removal of pollutants in the environment. It is based on electrokinetic migration across a supported liquid membrane (SLM) under the influence of an external electrical field between two aqueous compartments. Based on the features of the SLM and the electrical field, EME offers quick extraction, effective sample clean-up, and good selectivity, and limits the amount of organic solvent used per sample to a few microliters. In this paper, the basic devices (membrane materials and types of organic solvents) and influencing factors of EME are first introduced, and the applications of EME in the analysis and removal of environmental inorganic ions and organic pollutants are systematically reviewed. An outlook on the future development of EME for environmental applications is also given.
电膜萃取（EME）是一种近年来被广泛应用于环境中污染物分析与去除的小型化萃取技术。它基于在两个水相之间的外部电场影响下，通过支撑液膜（SLM）的电动迁移。基于支撑液膜和电场的特性，电膜萃取具有萃取速度快、样品净化效果好、选择性高的优点，并且将每个样品的有机溶剂用量限制在几微升。本文首先介绍了电膜萃取的基本装置（膜材料和有机溶剂类型）及影响因素，并系统综述了电膜萃取在环境无机离子和有机污染物分析与去除方面的应用。同时也对电膜萃取在环境应用中的未来发展进行了展望。
