Summary

Extraction of microamounts of yttrium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of 15-crown-5 (15C5,L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, HL2, +, YL3+, YL2, 3+and YH-1L2, 2+are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated with water have been determined.
