It was found that sulfuric acid, 2-naphthalenesulphonic acid and sulfurous acid could be effectively separated by competitive exchange adsorption in views of action force difference of the components with the resin. The exchange adsorption dynamic diffusion parameters were calculated with diffusion equation for solids and liquid films, and the rate-determining step was determined. The model of breakthrough curve for the resin bed was suggested, and applied to simulate the breakthrough process for each component.
