Abstract

Electromembrane extraction (EME) has emerged as a novel, versatile and efficient approach for sample preparation, widely applied across various scientific fields. Given the economic and industrial drive for maximum efficiency, the membrane in EME systems, a crucial part of the process, has been extensively studied. This has led to the development of multiple membrane formats, fabrication techniques, and modification approaches. The introduction and application of novel EME systems are particularly highlighted for complex analytes or samples, where maximum purification, recovery or elimination is desired. Additionally, EME offers significant advantages in reducing operation time and cost, making it particularly valuable in addressing environmental concerns. This review summarises the various membrane options, such as hollow fibers, flat sheets, polymer inclusions, and gel membranes, discussing their conventional fabrication methods with an emphasis on the advantages and general specifications of each. Furthermore, the review explores membrane modification approaches for improving EME performance, including solvent and polymeric support modifications, outlining specific applications, benefits, and future prospects. Challenges and limitations of these membrane options are also discussed.

电膜萃取中的聚合物膜支持物：各种选择、方法和修改概述

电膜萃取（EME）已成为一种新颖、多功能和高效的样品制备方法，广泛应用于各个科学领域。鉴于经济和工业对最高效率的追求，EME 系统中的膜作为该过程的关键部分已得到广泛研究。这导致了多种膜格式、制造技术和改性方法的发展。新型 EME 系统的引入和应用尤其突出了复杂分析物或样品，这些分析物或样品需要最大程度的纯化、回收或去除。此外，EME 在减少操作时间和成本方面具有显著优势，因此在解决环境问题方面特别有价值。本综述总结了各种膜选项，如中空纤维、平板、聚合物夹杂物和凝胶膜，讨论了它们的传统制造方法，重点介绍了每种膜的优势和一般规格。此外，综述还探讨了提高 EME 性能的膜改性方法，包括溶剂和聚合物支持改性，概述了具体应用、优点和未来前景。还讨论了这些膜选项的挑战和局限性。
