Abstract
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 have been determined. The data obtained allowed us to work out the extraction methods of separation and purification of berkelium from TPE, rare earths and several fission products using neutral organophosphorus compounds and high molecular weight amines.Keywords
