Abstract
Solvent extraction of microamounts of sodium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B−) in the presence of dodecaethylene glycol (DDEG, L) has been investigated. The equilibrium data have been explained assuming that the species HL+, H2L2+, NaL+ and NaHL2+ (L = DDEG) are extracted into the organic phase. The values of extraction and stability constants of the complex species in nitrobenzene saturated with water have been determined.
