Description

Though they were discovered in the 18th century, practical applications of individual lanthanides were not possible until the development of first ion exchange and later solvent extraction techniques. Today, solvent extraction using lipophilic organophosphorus complexants is the principal separation technique applied for lanthanide production by hydrometallurgy. Separations chemistry (coprecipitation, ion exchange, and solvent extraction) also was central to both the discovery of the individual actinides and to the preparation of samples of sufficient purity to allow elucidation of their chemical/physical properties. Solvent extraction, in the form of the PUREX process, has become the single most important separations process in actinide ... continued below

Solvent extraction, in the form of the PUREX process, has become the single most important separations process in actinide technology. In this report, the basic thermodynamics of extraction of actinide and lanthanide metal ions is discussed.
