Bifunctional organophosphorus extractants for actinide recovery and purification. [Dihexyl-N,N-diethylcarbamoylmethylenephosphonate (DBDECMP)]
Technical Report
·
OSTI ID:7094854
The extraction chemistry of carbamoylmethylenephosphonates is currently under investigation at Rocky Flats for actinide recovery and purification. An overview of the current research efforts on these extractants are presented. The extractants studied most include the case where the R's represent hexyl, butyl, and ethyl groups, such as DHDECMP (dihexyl-N,N-diethylcarbamoylmethylenephosphonate) and DBDECMP (dibutyl-N,N-diethylcarbamoylmethylenephosphonate). The bifunctional organophosphorus extractants are being investigated for various applications at Rocky Flats. The applications include plutonium and americium recovery from acidic waste streams, separation of plutonium from mixed actinide residues, and purification of americium. The mechanisms of the synergistic extraction of Am (III) and Pu (IV) by bifunctional extractants mixed with monofunctional organophosphorus compounds are presented. 2 figures, 2 tables.
