低共熔溶剂在萃取分离中的应用

随着绿色化学的不断发展,如何在分析过程中应用和体现绿色化学特点,避免分析过程对环境产生二次污染及对人员造成危害也得到了关注。开发和使用具有绿色化学特点的溶剂和方法是分析工作者努力的方向之一。在已经出现的新溶剂中,低共熔溶剂(DES)与离子液体(ILs)物理性质相似,并具有环境友好、不可燃、生物降解、价廉、易制备等特点,因而近几年来获得了迅速发展。该文总结了低共熔溶剂的制备、性质及分类,综述了近年来其在萃取和分离中的应用进展。

Applications of Deep Eutectic Solvent in Extraction and Separation

With the continued development of green chemistry,how to apply and reflect the characteristics of green chemistry in analysis process,avoiding the secondary pollution of the analysis process and the possible harm to the analysts have received an extensive attention.Therefore,the development and use of solvents with green chemistry characteristics is one of the main work for analysts.Deep eutectic solvents(DESs) are another type of solvents with similar physical properties to ionic liquids(ILs).Compared with ILs,DESs have showed some advantages such as environmental friendliness,non-combustibility,biodegradablity,low cost and simple preparation,etc.DESs have been used as green solvents in the extraction and separation of target compounds in different samples.The preparation,properties and classification of DESs are summarized this review,and their applications in extraction and separation are also presented.
