Electromembrane extraction (EME) is a novel sample preparation technique in pharmaceutical, chemical, clinical and environmental analysis. This technique uses electromigration across artificial liquid membranes for selective extraction of analytes and sample enrichment from complex matrices. This review focuses on the setup, general procedure and parameters affecting the extraction efficiency of EME. An overview of innovations in EME (on-chip EME, low voltage EME, drop-to-drop EME, pulsed EME and EME followed by low-density solvent based ultrasound-assisted emulsification microextraction) is also presented in this article and attention is focused on the use of EME for pharmaceutical, chemical, clinical and environmental analysis.
电膜萃取（EME）是一种应用于药物、化学、临床和环境分析领域的新型样品制备技术。该技术利用电迁移通过人工液膜，从复杂基质中选择性萃取分析物并实现样品富集。本文综述聚焦于电膜萃取的装置、一般流程以及影响萃取效率的参数。本文还概述了电膜萃取的创新进展（芯片上的电膜萃取、低电压电膜萃取、逐滴电膜萃取、脉冲电膜萃取以及电膜萃取结合基于低密度溶剂的超声辅助乳化微萃取），并重点关注电膜萃取在药物、化学、临床和环境分析中的应用。
