Electromembrane extraction (EME) was inspired by solid-phase microextraction and developed from hollow fiber liquid-phase microextraction in 2006 by applying an electric field over the supported liquid membrane (SLM). EME provides rapid extraction, efficient sample clean-up and selectivity based on the nature of the SLM and the electrical field. EME has been applied for the separation of ionizable compounds from complex samples, and EME is currently considered as an active research topic in the area of sample preparation and analytical chemistry. We expect that EME will play important roles in future analytical laboratories. This review summarizes and highlights the advancements in EME from 2006 to 2016 with focuses on 1) fundamental aspects, 2) device and operation modes, 3) performance, and 4) hyphenation to other analytical sample preparation techniques. Meanwhile, this review indicates that the main objectives for future EME is to establish EME as tool for routine applications, and to stimulate for further research on sophisticated systems based on the EME principle.

电膜萃取（EME）受固相微萃取的启发，并于2006年通过在负载的液膜（SLM）上施加电场而从中空纤维液相微萃取发展而来。EME根据SLM的性质和电场提供快速提取，有效的样品净化和选择性。EME已用于从复杂样品中分离可电离化合物，目前EME被认为是样品制备和分析化学领域的活跃研究主题。我们希望EME在未来的分析实验室中将发挥重要作用。这篇综述总结并突出了2006年至2016年EME的进展，重点是1）基本方面，2）设备和操作模式，3）性能，和4）联用其他分析样品制备技术。同时，该评论表明，未来EME的主要目标是将EME建立为常规应用程序的工具，并激发基于EME原理的复杂系统的进一步研究。
