EXTRACTION SEPARATION OF U(VI), Pu(IV) AND Am(III) FROM CARBONATE SOLUTIONS BY CARBONATE OF MTOA

The results of extraction separation of U(VI), Pu(IV) and Am(III) from carbonate solutions of carbonate of methyltrioctylammonium (MTOA). The maximum value of the separation factor of U(VI) and Pu(IV), amounted to 80.8, U(VI) and Am(III) - 57,9, Pu(IV) and Am(III) is 19.2. Shown the possibility of joint extraction of U(VI) and Pu(IV) in the organic phase and purification of the Am(III).
