The kinetics of extraction of alkylpyrocatecholates of europium, americium, curium, and californium from solutions containing 0.01-1.5 M potassium carbonate at pH = 10.5-13.2 has been studied. It has been shown that extraction slows down with increase of concentration of the complexing agent and accelerates with rise of pH. The chemical stage limiting the extraction rate seems to proceed on the aqueous phase slide. The conditions of americium(III) and curium(III) separation by extraction chromatography have been determined making use of the kinetic data.
