Description

From the extraction experiments and γ-activity measurements, the extraction constant corresponding to the Rb+(aq)+CsL+(nb) <--> RbL+(nb)+Cs+(aq) equilibrium in the two-phase water-nitrobenzene system (L = valinomycin; aq = aqueous phase, nb = nitrobenzene phase) was evaluated in the form log Kex(Rb+, CsL+) = 0.9. Further, the stability constant of the valinomycin-rubidium complex in nitrobenzene saturated with water was calculated as log βnb(RbL+) = 11.7. (author)
