"Extraction of microamounts of calcium and strontium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of 1,2-bis(diphenylphosphino) ethane dioxide (DPPEtDO, L) has been investigated. The equilibrium data have been explained assuming that the species HL+, HL2+ , ML22+ and ML32+ (M2+ = Ca2+, Sr2+) are extracted into the organic phase. The values of extraction and stability constants of the cationic complexes in nitrobenzene saturated with water have been determined. In the considered nitrobenzene medium, it was found that the stability constants of the complexes CaL22+ and CaL32+, where L is DPPEtDO, are somewhat higher than those of the corresponding complex species SrL22+ and SrL32+ with the same ligand L." .
