摘　　要：离子液体分离技术主要用于水中微量、痕量组分的分离与富集,也可用于水中有机污染物的去除,在许多方面优于传统的分离技术。离子液体分离技术的研究主要分为两个方向:离子液体双水相萃取技术和离子液体气浮溶剂浮选技术。综述了这两种技术的装置、影响因素、机理及应用,并指出了这两种技术的复合——离子液体双水相气浮溶剂浮选技术是今后的发展方向。Ionic liquids have been applied to separation and concentration of trace component in water,also used in removing the organic pollutants,and it is superior to traditional separation technologies in many ways.The research of ionic liquids aqueous two-phase technologies have been divided into two directions：ionic liquid aqueous two-phase extraction technology and ionic liquid aqueous solvent flotation technology.The two technologies was discussed from four aspects including installations,influencing factors,mechanism and applications.And it based on the two technologies,there is a broad prospect via reasonable design,advantageous combination and modeling optimization.
