摘要：
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. The 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 a(Sr/Y) in the system with B15C5 presents the same order of magnitude as that for 15C5.
