摘要：
Extraction of microamounts of cesium by nitrobenzene solutions of sodium, ammonium and thallium dicarbollylcobaltates (M+B−; M+ = Na+, NH4+, Tl+) in the presence of benzo-15-crown-5 (B15C5, L) has been investigated. The equilibrium data have been explained assuming that the complexes ML+ and ML2+ (M+ = Na+, NH4+, Tl+; L = B15C5) are present in the organic phase. The stability constants of the complex species ML+ and ML2+ in nitrobenzene saturated with water have been determined.
