Abstract

Extraction of AmIII and LnIII from NaClO4 medium with di2ethylhexyldithiophosphoric acid DEHDTP di2ethylhexylmonothiophosphoric acid DEHMTP di2ethylhexylmonothiophosphinic acid DEHMTPI dihexyldithiophosphinic acid DHXDTPI diheptyldithiophosphinic acid DHPDTPI dioctyldithiophosphinic acids DODTPI dinonyldithiophosphinic acid DNDTPI di1methylheptyldithiophosphinic acid DMHDTPI and di2ethylhexyldithiophosphinic acid DEHDTPI in xylene has been investigated The order of the extraction selectivity for AmIII is DEHDTPI DEHDTP DEHMTPI DEHMTP DHPDTPI DODTPI DHXDTPI DNDTPI DMHDTPI DEHDTPI DODTPI for extractants with 2ethylhexyl alkyl straight chain alkyl branch chain alkyl respectively Using 01 mol/l NaClO4 solution as aqueous phase the slope values of the logDpH and logDlogC curves are not integers and the slope values for AmIII are slightly higher than those for EuIII for all extractants The relationship between the slope value and extraction conditions can be described as logS = algC HA/C M S/4+b In the presence of macro EuClO43 the formula logSF Am/Ln = B2logC HLD Ln/D Ln + 1C Eu can well describe the relationship between separation factor and the extraction condition A high separation factor SF Am/Eu = 2500 is obtained by solvent extraction with 05 mol/1 DEHDTPI in toluene from 1 mol/l NaNO3 solution
