摘　　要：CO2在离子液体中的溶解度是离子液体捕集CO2过程的关键数据,而溶解度的准确数据来源有两个:实验测定和模型化方法。本文介绍了测压法、称重法、测压称重联用法、CO2流量法、静态法和色谱法等6类实验测定方法,同时根据各种模型中离子液体"分子模型"的不同分类概述了近年来CO2在离子液体中溶解度模型化方法的研究进展,评述了各种模型应用于离子液体体系的研究前景。Solubility of CO2 in ionic liquids（ILs）is the most important data in the research on CO2 captured ILs,while the accurate data come from two sources：experimental determination and modeling methods.This article summarizes six kinds of experimental methods including pressure measuring,weight measuring,combined pressure-weight measuring,CO2 flow measuring,static method,and chromatography method.Meanwhile,this contribution aims to review the different modeling approaches that have been used to predict solubility of CO2 in ILs according to the ＂molecular model＂ used to describe the ILs in the different models,highlighting the most important efforts done in the last years.
