Abstract
- The effect of the presence of valinomycin in lecithin membrane on its interfacial tension has been studied. The experiments have been carried out at various forming solution compositions and at various potassium ion concentrations in electrolyte solution. Potassium chloride was used as the electrolyte. A complex was formed between the valinomycin molecule and K + ion. The following parameters describing the complex were determined: K , the stability constant of the valinomycin–K + complex and B , partition coefficient. These values are equal to 3.52 × 10 5 m 3 mol −1 and 6.0, respectively.
