Resumen de Lonic liquids for metal lon separation

Yu Liu, Ji Chen

• lonic liquids (ILs) as important green solvents and extractants have showed potential application in separation of metal ions. In this chapter, we present new developments in our lab and others to use ILs for green separation of metal ¡ons, such as rare earths (REs) and heavy metal ¡ons, especially by the IL-functionalized solid adsorption materials. The important fundamentals and applied studies on metal ¡on separation are commented, which include the synthesis of ILs, the new separation systems of ILs, new task-specific ILs (TSILs), and complex materials composed of ILs and inorganic and organic polymers as adsorption materials for liquid-liquid and liquid-solid separation. This chapter only discusses frequently used ILs for metal ion separation; for more information of ILs, some reviews may be referred.
