Application of Ionic Liquids on Rare Earth Green Separation and Utilization

This book comprehensively details the applications of ionic liquids in rare earth green separation and utilization based on the unique interactions of ionic liquids with rare earth ions. It consists of nine chapters demonstrating the synthesis and properties of ionic liquids, coordination chemistry of ionic liquids and rare earth, ionic liquids as diluents, extractants, adsorption resins for rare earth extraction and separation, electrodeposition of rare earth metals in ionic liquids, and preparation of rare earth material with the aid of ionic liquids. It is both interesting and useful to chemists, metallurgists and graduate students working on fundamental research of ionic liquids as well as professionals in the rare earth industry. It provides considerable insights into green chemistry and sustainable processes for rare earth separation in order to meet the environmental challenge of rare earth metallurgy around the globe, especially in China.

Ji Chen is a Professor of Chemistry at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, China.

Ji Chen obtained his doctorate from the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences (CAS), in 1999. He was a postdoctoral researcher at the Institute of Chemical Metallurgy, CAS, from 1999 to 2001. Then he worked at the Kanazawa University, Japan and the University of Alabama, USA, from 2002 to 2004. He has been appointed as a professor of chemistry at Changchun Institute of Applied Chemistry since 2004. Among his current interests are the utilization of ionic liquids (ILs) as extraction media or extractants and ILs functionalized solvent impregnated resin for the extraction and separation of rare earth and related metal ions, the interaction of extractant with rare earth and the mechanism of interfacial mass transfer, the clean rare earth separation techniques at an industrial scale for Bayan Obo rare earth ore with mixed bastnasite and monazite and ion-adsorbed rare earth deposits in South China.
