Solvent extraction of strontium and barium into nitrobenzene by using hydrogen dicarbollylcobaltate in the presence of dicyclohexano-24-crown-8

Journal of Radioanalytical and Nuclear Chemistry, 2009
Extraction of microamounts of strontium and barium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B−) in the presence of dicyclohexano-24-crown-8 (DCH24C8, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, \( {\text{HL}}_{2}^{ + }, \) ML2+ and \( {\text{ML}}_{ 2}^{2 + } \) (M2+ = Sr2 ...
