The work presents the results of an investigation of the electrochemical oxidation of berkelium(III) on a platinum mesh electrode in a two-phase system 0.5 M D/sub 2/EHPA-HNO/sub 3/ and the stability of berkelium(IV) in the organic phase in the case of its contact with water. The influence of the potential of the working electrode, time of electrolysis, concentration of berkelium, HNO/sub 3/, extraction reagent, and curium as the source of internal /alpha/ radiation, as well as the nature of the diluent on the degree of extraction of berkelium(IV) into the organic phase was determined. The law of the rate of the process of extraction of berkelium (IV) into the organic phase, satisfactorily describing the experimental data obtained, was established.
