The applicability of simplified models for the determination of ion exchange diffusion coefficients in zeolites is examined. The simplified models examined are Vermeulen's, Paterson's, and Nernst-Plank's approximations for isotopic and ion exchange processes, used in ion exchange systems analysis. P
Measurements have been made of the interdiffusion coefficient in Zeo-karb 225,s % DVB, ion-exchange resin for the exchange of Hf and Na+ ions. By carrying out a series of 12 differential runs, the variation of the interdiffusion coefficient with resin composition has been determined. The results sho
