Extraction of microamounts of calcium, strontium and barium into nitrobenzene by using hydrogen dicarbollylcobaltate in the presence of dibenzo-18-crown-6

Extraction of microamounts of calcium, strontium and barium into nitrobenzene by using hydrogen dicarbollylcobaltate in the presence of dibenzo-18-crown-6

Extraction of microamounts of calcium, strontium and barium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H + B − ) in the presence of dibenzo-18-crown-6 (DB18C6, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL + , ML 2+ , ML 2 2+ and...

Description
Summary:Extraction of microamounts of calcium, strontium and barium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H + B − ) in the presence of dibenzo-18-crown-6 (DB18C6, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL + , ML 2+ , ML 2 2+ and MHL 2 3+ (M 2+ = Ca 2+ , Sr 2+ , Ba 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.
