Abstract: Extraction of microamounts of strontium with a nitrobenzene solution of hydrogen dicarbollylcobaltate in the presence of benzo-15-crown-5 (L) has been investigated. The equilibrium data have been explained assuming that the complexes HL⁺, HL₂⁺, and SrL₂²⁺ are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated with water have been determined.
