Abstract
Extraction of cesium by the nitrobenzene solution of bis-1,2-dicarbollylcobaltate in the presence of dibenzo-18-crown-6 (DB18C6, L) was investigated. It was found, that besides hydrated cesium ion Csorg+ the complexes CsLorg+ and CsL2,org+ were extracted to nitrobenzene phase. No maximums on dependencies of the cesium distribution ratio (D) on the concentration of crown in the systemcL was found andD increased monotony withcL. Values of extraction constants and stability constants of extracted species in nitrobenzene have been determined.
