| Abstract: | Summary Extraction distribution of microamounts of cesium in the water-HCl-nitrobenzene-dibenzo-18-crown-6(L)-hydrogen dicarbollylcobaltate
has been investigated. The equilibrium data have been explained assuming that the complexes HL+, CsL+and CsL2,+are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated
with water have been determined. |
