Extraction of microamounts of calcium into nitrobenzene using hydrogen dicarbollylcobaltate in the presence of PEG 400

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 polyethylene glycol ligand PEG 400 (L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+and CsL+are extracted into the organic phase.
