Abstract
The combination of Raman spectrometry and radiotracer techniques allow ed accurate measurements of ion-exchange kinetics. The exchange of chl oride for benzoate or benzenesulphonate ions was studied. These ions w ere selected as models to simulate the fouling of membranes, a major i nconvenience frequently encountered in membrane processes, especially in bio-industries. The experimental data were compared with the theore tical treatment proposed for two possible hypotheses, namely particle or film diffusion.
