Solvent extraction of cesium into nitrobenzene by using a synergistic mixture of hydrogen dicarbollylcobaltate and polypropylene glycol PPG 425

Journal of Radioanalytical and Nuclear Chemistry, 2010
Extraction of microamounts of cesium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B−) in the presence of polypropylene glycol PPG 425 (L) has been investigated. The equilibrium data have been explained assuming that the complex species HL+ and CsL+ (L = PPG 425) are extracted into the organic phase.

Extraction of microamounts of calcium in the two-phase water-HCl-18-crown-6-nitrobenzene-hydrogen dicarbollylcobaltate system

Journal of Radioanalytical and Nuclear Chemistry, 2006
Extraction of microamounts of calcium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of 18-crown-6 (18C6, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, CaL2+and CaL are extracted into the organic phase.
