- Abstract
Extraction of microamounts of strontium and barium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B−) in the presence of dibenzo-21-crown-7 (DB21C7, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, ML2+, ML and MHL (M2+ = Sr2+, Ba2+) are extracted into the organic phase. The values of extraction and stability constants of the species in nitrobenzene saturated with water have been determined.
