Chelate Extraction of Metals into Ionic Liquids

2011 Solvent extraction research and development, Japan  
In the solvent extraction of metal cations into ionic liquids, use of Brønsted acid-type chelate extractants has some advantages including simplicity in controlling extraction selectivity by selecting suitable aqueous phase pH values and simple back-extraction recovery of the extracted metals using acid solutions. In this review, various fundamental and applied research on metal extraction using the "ionic liquid chelate extraction system" since 2001 are described in detail.
