摘要：

Extraction of microamounts of strontium by a nitrobenzene solution of potassium dicarbollylcobaltate (K+B-) in the presence of 15-crown-5 (15C5, L) has been investigated. The equilibrium data have been explained assuming that the complexes KL+, KL2+ 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. © 2006 Akadémiai Kiadó.
