Five kinetic models potentially applicable to ion exchange with ions of high selectivity, discussed in Part I of this study, are systematically applied to experimental data on chloride/sulfate forward and reverse exchange and sulfate isotopic exchange with three different types of resins (quaternary ammonium, tertiary amine, and secondary amine groups) and highly dilute solutions (< 0.006 N). Interpretation of these data shows conceivably that the system is controlled by film diffusion, with a small contribution from intraparticle diffusion in forward and isotopic exchange and especially for the resin of highest sulfate selectivity.

Abstract
Five kinetic models potentially applicable to ion exchange with ions of high selectivity, discussed in Part I of this study, are systematically applied to experimental data on chloride/sulfate forward and reverse exchange and sulfate isotopic exchange with three different types of resins (quaternary ammonium, tertiary amine, and secondary amine groups) and highly dilute solutions (< 0.006 N). Interpretation of these data shows conceivably that the system is controlled by film diffusion, with a small contribution from intraparticle diffusion in forward and isotopic exchange and especially for the resin of highest sulfate selectivity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
