Owing to the growing emphasis on development of green and sustainable processes in extraction and separation technologies, interest in ionic liquid (IL)–based aqueous biphasic systems (ABSs) has significantly amplified for extraction and separation of value-added compounds. The ability of IL-based ABS to act as alternative solvents for non-biocompatible volatile organic compounds provided strength to green and sustainable aspect. The field of IL-based ABS has undergone much development over years with respect to phase constituting components, factors such as temperature and pH in extraction of wide variety of chemical compounds. This work provides an overview of recent developments of IL-based ABS and the mechanistic aspects of phase formation and extraction processes. Moreover, future prospects and challenges are highlighted as addressed for further expansion.

由于越来越重视在提取和分离技术中绿色和可持续工艺的发展，人们对基于离子液体（IL）的水性双相系统（ABS）的兴趣大大增加了对增值化合物的提取和分离。基于IL的ABS充当非生物相容性挥发性有机化合物的替代溶剂的能力为绿色和可持续发展方面提供了力量。基于IL的ABS领域在相组成成分，多种化合物的提取中的温度和pH等因素方面已经历了多年的发展。这项工作概述了基于IL的ABS的最新发展以及相形成和萃取过程的机理方面。此外，
