Extraction Separation of Strontium and Yttrium Radionuclides by Hydrogen HeptachloroDicarbollylcobaltate in the Presence of Benzo 15 Crown 5
Original language description
Extraction of strontium and yttrium by the nitrobenzene solution of H+-form of heptachloro -bis 1,2 dicarbollylcobaltate (H+B ) in the presence of benzo-15-crown-5 (B15C5, L) has been investigated. Presence of B15C5 leads to a great synergistic effect for the extraction of strontium and an antagonistic effect for the extraction of yttrium. The extraction constants of Sr2+ complexes of B15C5 were determined. The separation factor (Sr/Y) in the system with B15C5 presents the same order of magnitude as that for 15C5. The main limit of extraction efficiency is separation of the aqueous and organic phase.
