Extractants for rare earth metals

Abstract

The separation of trivalent rare earth metals is perhaps the most serious challenge associated with a closed fuel cycle. The choice of ligand as extractant, which must be selective and efficient in conditions of high radiation environment, plays an important role. In this review there are the main examples of extractants for f-elements used in the present 10–20 years.
