The extraction behaviour of berkelium (IV) from inorganic acid solutions using neutral organophosphorus compounds and high molecular weight amines was studied. Distribution coefficients as a function of the nature and concentration of acid, extractant, organic solvent and oxidant were examined. The stoichiometry of Bk(IV) extraction has been studied and the composition of the extracted species has been determined. The data obtained allowed the authors to work out the extraction methods of separation and purification of berkelium from transplutonium elements, rare earths and several fission products using neutral organophosphorus compounds and high molecular weight amines. 8 figures, 2 tables.
