This review examines the recent trends and developments in membrane-based extraction technology, with a focus on supported liquid membrane (SLM) extraction. This paper attempts to review the studies on polymeric membrane extraction, relating to mass transfer, stability, fluxes and performance. Prospects for future research, on the use of membrane extraction for in-situ product removal of chiral amines, are presented as well. The main challenge of the current state-of-the-art membrane extraction technology is limited SLM-stability. Conventionally, polymeric membrane materials are used as an SLM-support. The use of ceramic membranes, either with or without surface modification, should be looked at as a possible means of stability enhancement. The use of ionic liquids as the solvent for membrane impregnation is already studied intensively in literature. However, the performance of a certain IL is strongly dependent on the system at hand. Techniques such as hollow fibre renewal liquid membranes and polymer inclusion membranes, can also increase membrane stability and are discussed further. Lastly, the industrial application potential of membrane extraction is hindered by the lack of scaled-up pilot plants, which is addressed as well.

本综述审查了基于膜的提取技术的最新趋势和发展，重点是支持的液膜 (SLM) 提取。本文试图回顾聚合物膜萃取的研究，涉及传质、稳定性、通量和性能。未来研究的前景，在原位膜提取中的应用还介绍了手性胺的产物去除。当前最先进的膜提取技术的主要挑战是有限的 SLM 稳定性。通常，聚合物膜材料用作 SLM 支撑。陶瓷膜的使用，无论是否经过表面改性，都应被视为一种可能的稳定性增强手段。文献中已经深入研究了使用离子液体作为膜浸渍的溶剂。但是，某个 IL 的性能在很大程度上取决于手头的系统。中空纤维更新液膜和聚合物包裹膜等技术也可以增加膜的稳定性并进一步讨论。最后，由于缺乏规模化的中试工厂，膜提取的工业应用潜力受到阻碍，
