Solvent extraction of plutonium(IV) polymer by dihexyl-N, N-diethyl-carbamoylmethylphosphonate (DHDECMP)

Journal Article · · Sep. Sci. Technol.; (United States)

The bifunctional organophosphorus compound DHDECMP (dihexyl-N, N-diethylcarbamoylmethylphosphonate) is effective in the extraction of hydrolytic plutonium(IV) polymer from both 0.04 and 7.0M nitric acid. Stripping the polymer is difficult, even with hydrofluoric acid. However, 1.0M sodium carbonate is a very effective stripping agent. The extracted complex contains one to two molecules of DHDECMP per plutonium ion and the plutonium(IV) maintains a polymeric structure. 15 references, 3 figures, 5 tables.
