Summary

From extraction experiments and γ-activity measurements, the extraction constant corresponding to the equilibrium Li+(aq)+NaL+(nb) ↔LiL+(nb)+Na+(aq) taking place in the two-phase water-nitrobenzene system (L = valinomycin; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as logK ex(Li+,NaL+)=-1.1. Further, the stability constant of the valinomycin-lithium complex species in nitrobenzene saturated with water was calculated: logβ nb(LiL+)=6.3.
