| Abstract/Summary |
Extraction of microamounts of strontium with a nitrobenzene solution of ammonium dicarbollylcobaltate in the presence of 15-crown-5 (L) has been investigated. The equilibrium data have been explained assuming that the complexes NH4L+, NH4L+2 , and SrL2+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.
