Progress of Separation and Determination Methods for Rare Earth Elements

摘要

This review covers the developments in rare earth elements analysis over the period from 2003 to 2005. Some novel separation and determination methods and their applications in rare earth elements analysis were presented and discussed in detail. Some new materials, such as ionic liquids, nanometer materials and ion-imprinted polymers, and some new technologies, such as cloud point extraction, membrane extraction and capillary electrophoresis were successful used in rare earth elements analysis. The determination methods of NAA, ICP-OES and ICP-MS were also discussed in detail.
