摘要：
From extraction experiments and gamma-activity measurements, the exchange extraction constants corresponding to the general equilibrium C (+)(aq) + 1 center dot Cs+(nb) 1 center dot C+(nb) + Cs+(aq) taking place in the two-phase water-nitrobenzene system (C+ = organic cation, 1 = hexaarylbenzene-based receptor; aq = aqueous phase, nb = nitrobenzene phase) were evaluated. Furthermore, the stability constants of the 1 center dot C+ cationic complex species in nitrobenzene saturated with water were calculated.
