Research Progress in Extraction and Separation of Heavy Metal Ions by Ionic Liquids

随着近几年绿色化学的兴起,室温离子液体的出现给传统的萃取分离注入了新的内容。离子液体具有不易挥发、导电性强、黏度大、蒸气压小、性质稳定、可设计性等优点,因而在萃取分离和化学反应领域显示出良好的应用前景。本文概述了离子液体的发展、分类、特点,综述了近年来离子液体萃取分离重金属离子方面的研究,并对其发展提出建议。

With the rise of green chemistry in recent years, the emergence of room temperature ionic liquids has injected new content into traditional extraction and separation. Ionic liquids have the advantages of low volatilization, strong electrical conductivity, high viscosity, small vapor pressure, stable nature, and designability. Therefore, it have shown good application prospects in the fields of extraction separation and chemical reaction. This paper summarized the development, classification and characteristics of ionic liquids, and reviewed recent studies on the separation and separation of heavy metal ions by ionic liquids, and proposed suggestions for their development.
