Abstract

Liquid-phase extraction and sorption (solid-phase extraction) of AmIII, EuIII, UVI, and TcVII with alkyl (N,N-dibutylcarbamoylmethyl)methylphosphinates (ADM) from nitric acid solution were studied. The solvate numbers of extracted UVI, AmIII, EuIII, and TcVII complexes and the separation factors for AmIII/EuIII (f Am/Eu), TcVII/EuIII (f Tc/Eu), and UVI/TcVII (f U/Tc) pairs were determined. It was shown for the extraction of AmIII and sorption of PuIV that various ADM derivatives are most efficient for the extraction and sorption concentration of actinides: the heptyl derivative (C7) is efficient for extraction and the decyl derivative (C10) is most efficient for sorption.
