Abstract
Series of experiments were performed to show the influence of the concentration and flow rate of solution on the self‐diffusion of the iodide ion into the ion‐exchange resin Dowex 1 × 8. Using a model based on the concept of an effective diffusion layer with the nonlinear concentration profile, rate curves were calculated and compared with experimental results. Good fitting in the whole concentration and flow range is observed. Using the same model, concentration profiles in both solid and liquid phases for three different thicknesses of the diffusion layer were calculated.Keywords
