• The apparent interdiffusion of counter-ions in anion exchange membrane Selemion ASV was investigated. The experimental results show that the rate of interdiffusion is controlled by combined film diffusion and membrane diffusion at low flow rate, but controlled by membrane diffusion alone at high flow rate. The relationships between the apparent interdiffusion coefficient and temperature can be expressed by the Arrhenius equation for various systems. The apparent interdiffusion coefficient arid interdiffusion activation energy for various systems have the ordersDOH-Br>DOH-C1>DOH-NO3>DOH-I ?? DOH-SO4 AND EOH-Br<E>SbOH-C1<E>SbOH-I, respectively. The interdiffusion of counter ions is independent of the kinds of co-ions at low concentration of the solution. There are an increase of integral interdiffusion coefficient and a decrease of interdiffusion activation energy with increasing bulk concentration of the electrolyte solution.
