Transport of Some Strong Incompletely Dissociated Acids through Anion-exchange Membrane

Original language description

Nitric and sulfuric acids belong among strong incompletely dissociated acids, so that in the description of their transport through an ion-exchange membrane, ionic equilibria have to be taken into account. The paper presents the determination of ionic mobilities and diffusivity of non-dissociated form of these acids. For that purpose, data on the dialysis experiments with nitric and sulfuric acids in a batch mixed cell with an anion-exchange membrane NEOSEPTA-AFN, which have been completed by those on the membrane conductivity, have been used. The dependencies of ionic mobilities and diffusivity of non-dissociated form of nitric acid upon the acid concentration in the membrane have been approximated by the second degree polynomials. Their coefficientshave been determined by the numerical integration of the partial differential equation describing the concentration fields of the acids in the membrane and liquid films on both the sides of the membrane followed by an optimizing procedure
