From extraction experiments and γ-activity measurements, the extraction constant corresponding to the equilibrium occurring in the two-phase water-nitrobenzene system (1 = nonactin, aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log K ex (Ag + , 1 ⋅ Na + ) = 0.6 ± 0.1. Furthermore, th...
