Stability of complex of Cs+ with valinomycin in nitrobenzene saturated with water

  • E. Makrlík
  • P. Vañura


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