Abstract

From extraction experiments and γ-activity measurements, the extraction constant of the Ba2+ (aq)+SrL2/2+(nb)⇆⇆BaL2/2+ (nb)+Sr2+(aq) equilibrium taking place in a two-phase water-nitrobenzene system (L=15-crown-5; aq-aqueous phase, nb=nitrobenzene phase) was evaluated as logKex(Ba2+,SrL2/2+)=1.8. Further, the stability constant of the BaL2/2+ complex in water saturated nitrobenzene was calculated to be log βnh(BaL22+)=16.5.
