- Abstract
From extraction experiments and γ-activity measurements, the exchange extraction constants corresponding to the general equilibrium M (aq) + CsL (nb) ⇔ ML (nb) + Cs (aq) taking place in the two-phase water-nitrobenzene system (M = K, Rb, $$ {\text{NH}}_{4}^{ + } $$, Ag, Tl; 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: $$ {\text{NH}}_{4}^{ + } $$ < K < Ag < Rb < Tl.
