摘要：

A method for estimating the interfacial potential difference in electromembrane systems with alkaline solutions of amino acids is developed. Systems with MA-41 anion-exchange membranes and aqueous sodium hydroxide solutions with glycine are investigated. It is found that in solutions with alkali concentrations greater than 0.010 M, the interfacial potential difference decreases logarithmically, i.e., in agreement with the Donnan relationship. At the same time, in weakly alkaline solutions of glycine, in which the amino-acid concentration exceeds that of the alkali, an increase in the interfacial potential difference is observed. This may be due to a disturbance of the equilibrium of the protolytic reaction in the membrane on the side where hydroxide ions form.
