Abstract

Extraction of cesium with a nitrobenzene solution of bis[undecahydro-7,8-dicarbaundecaborato(2-)]cobaltate(1-) in the presence of 18-crown-6 (18C6, L) has been investigated. The equilibrium data and typical dependences of the Cs distribution ratios on the analytical concentration of 18C6 in the system under study can be explained assuming that the complexes HL<sup>+</sup>, CsL<sup>+ </sup>and CsL<sub>2</sub><sup>+</sup> are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated with water have been determined.
