中文摘要： 因离子液体的结构可设计性强使其在应用中可实现"量体裁衣"，而多数应用主要利用其挥发性小这一特征，结构可设计性的特征较少体现，特别是萃取分离。同时离子液体的应用很少和性质研究全面系统地相结合。本项目以我国水污染排放标准中严格限制的挥发酚为对象，根据其常用萃取剂的结构特征和萃取机理，选择含有S=O/C=O/P=O官能团的离子液体，系统全面地研究热力学性质，在此基础上探讨其在分散液相微萃取系统中处理挥发酚的性能。首先对离子液体进行热力学性质研究，主要包括纯组分和两组分系统的性质。然后，利用这些数据及数据处理结果从理论上对萃取性能进行分析、解释。最后，进一步通过光谱数据从实验角度解释萃取机理，验证功能化离子液体设计的初衷。申请者近年一直从事离子液体的性质及其萃取性能的研究，现已合成出含有S=O的离子液体。本项目为功能化离子液体的设计提供理论指导，同时实现离子液体的性质研究和应用研究的有机结合。

英文摘要： Recently，ionic liquids (ILs) have attracted great attention in green chemistry due to their unique properties, e.g., extremely low vapor pressure and easy to be modified structurally to elicit desired physical properties. ILs have been applied in various aspects, such as biocatalysis, electrochemistry and separation. However, most research work just takes the advantage of low vapor pressure of ILs but not the both advantages of the above mentioned. Furthermore, the investigation of physical properties of ILs is just focus on the theory and not bombined with the application. Phenol and its derivatives are are listed as priority pollutants due to the potential harm to human health and environment. According to structure of the extractants for phenol, task-specific ionic liquids (TSILs) with S=O/C=O/P=O structure are used for phenol extraction based on dispersive-liquid phase microextraction (DLPME) in this program. 1) The thermodymnamic properties of TSILs systems, including unary, binary and ternary systems will be systematically investigated to provide fundamental data and theory for the application in extraction. 2) The application of TSILs in phenol extraction will be investigated and the explaination for the extraction should be given from the point of thermodynamics. 3) The mechanics of TSILs for phenol extr
