Near-quantitative recovery of actinides from nitric acid waste streams by solvent extraction using DHDECMP (dihexyl-N,N-diethylcarbamoylmethylphosphonate)

Conference ·
OSTI ID:6847613
The more-than-adequate extraction of actinides from high nitrate solutions and of efficient back-extraction from low nitrate solutions make DHDECMP the preferred extractant for this application. Isopar-diluted DHDECMP extraction data are presented herein. Comparative extraction data for Am(III) Pu(IV), and U(VI) are also presented. The behavior of these three actinides can be assumed to represent the general behavior of other actinides in their trivalent, tetravalent, and hexavalent oxidation states. 4 refs., 5 figs.
