摘要：

From extraction experiments and -activity measurements, the exchange extraction constants corresponding to the general equilibrium M+ (aq) + NaL+ (nb) a double dagger" ML+ (nb) + Na+ (aq) taking place in the two-phase water-nitrobenzene system (M+= Li+, H3O+, NH4 (+); L = calix[4]arene-bis(t-octylbenzo-18-crown-6); aq = aqueous phase, nb = nitrobenzene phase) were evaluated. Furthermore, the stability constants of the ML+ complexes in nitrobenzene saturated with water were calculated; they were found to increase in the following cation order: H3O+ < Li+ < NH4 (+).
