Distribution of Microamounts of Cesium in the Two-Phase Water-HCl-Nitrobenzene-2,3-Naphtho-15-crown-5-Hydrogen Dicarbollylcobaltate Extraction System.
Extraction of microamounts of cesium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of 2,3-naphtho-15-crown-5 (N15C5, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, HL+2, CsL+ and CsL+2 are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated with water have been determined.
