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 Cs +org the complexes CsL +org and CsL +2,org were extracted to nitrobenzene phase. No maximums on dependencies of the cesium distribution ratio (D) on the concentration of crown in the systemc L was found andD increased monotony withc L. Values of extraction constants and stability constants of extracted species in nitrobenzene have been determined.
