摘　　要：以咪唑基离子液体为代表,综述了近期普通咪唑基离子液体、功能咪唑基离子液体、支撑咪唑基离子液体和聚合咪唑基离子液体在分离固定CO2方面的研究进展,说明了各类咪唑基离子液体分离固定CO2的可行性及优缺点,并总结了离子液体固定CO2的影响因素和分离机制。The solubility of carbon dioxide in traditional room-temperature ionic liquids（RTILs）,functionalized ionic liquids or task-specific ionic liquids（TSILs）,supported ionic-liquid membranes（SILMs） and polymerized ionic liquids（poly（RTIL）） are summarized.The absorption capacity of TSILs is greater than that of RTILs,but the high viscosity of TSILs can be an operational drawback.SILMs show remarkably high selectivity compared to polymeric membranes,however,the instability of SILMs is recognized as a serious problem.This brief survey of the current development on the imidazolium cation ionic-liquid mediated CO2 capture suggests that CO2 capture by ionic liquids is a feasible practice.
