The combination of Raman spectrometry and radiotracer techniques allowed accurate measurements of ion‐exchange kinetics. The exchange of chloride for benzoate or benzenesulphonate ions was studied. These ions were selected as models to simulate the fouling of membranes, a major inconvenience frequently encountered in membrane processes, especially in bio‐industries. The experimental data were compared with the theoretical treatment proposed for two possible hypotheses, namely particle or film diffusion.
