Abstract
Extraction of microamounts of barium with a nitrobenzene solution of cesium dicarbollylcobaltate (Cs+B-) in the presence of 18-crown-6 (18C6, L) has b een investigated. Equilibrium data have been explained assuming that the co mplexes CsL+, CsL2+, BaL2+ and BaL22+ are extracted into the organic phase. Values of extraction and stability constants of the species in nitrobenzen e saturated with water have been determined.
