摘要
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 logKex (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.
