摘要：
From extraction experiments and gamma-activity measurements, the extraction constants corresponding to the equilibrium Cs+(aq) + + Cl-(aq) + L(nb) reversible arrow CsL+(nb) + Cl-(nb) in the two-phase water-nitrobenzene system (L valinomycin; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log K-ex(CsL+,Cl-) = 2.2. Further, the stability constant of the valinomycin-cesium complex in nitrobenzene saturated with water was calculated:log B-nb(CsL+) = 10.1.
