Abstract
Neutral bifunctional organophosphorus solvent extractants, such as dibutyl- N, N-diethylcarbamoylmethylphosphonate (DBDECMP) and its dihexyl analog extract appreciable amounts of trivalent lanthanides and actinides from nitric acid solutions. A brief overview of the lanthanide and actinide extraction chemistry of these extractants is given along with examples of possible technological applications. The results of selected research studies on the separation of actinides and lanthanides in mixed nitric acid-chloride solutions using DBDECMP are described.
