摘　　要：研究离子液体的分离与回收对于减少离子液体对环境的影响、提高离子液体的利用效率、降低离子液体的应用成本、促进离子液体的工业应用具有重要的意义.本文重点综述了利用无机盐-离子液体双水相、糖-离子液体双水相、聚合物-离子液体双水相和CO2诱导的离子液体双水相技术分离回收离子液体的研究进展,分析了影响离子液体分离回收的关键因素,评价了不同离子液体双水相体系的优缺点,展望了该领域的发展方向及面临的挑战.The investigation on the separation and recovery of ionic liquids from water would be of great importance in reducing environmental impact of ionic liquids, enhancing their utilization efficiency, decreasing their industrial cost and promoting their industrial application. In this review, we focused our attention on the research progress in the recovery of ionic liquids by using salt ＋ ionic liquid aqueous two-phase systems, sugar ＋ ionic liquid aqueous two-phase systems, polymer ＋ ionic liquid aqueous two-phase systems, and carbon dioxide induced aqueous two-phase systems. The main influence factors on the recovery of the ionic liquids were analyzed, and advantages and disadvantages of different ionic liquid aqueous two-phase systems were evaluated. The development in the ionic liquid recovery was prospected and the challenges were stressed.
