The steric effect of the functional groups on the kinetic properties of the chelating cellulose ion exchanger OSTSORB SALICYL is demonstrated. The exponential dependence was found between the diffusion coefficient and the concentration of the ion-exchanging functional groups and, together with its total mass capacity and its content of water, it has been used for the estimation of the sorbent kinetic properties. Moreover, the results obtained show that the attempt to achieve the highest possible capacity of the ion exchanger can lead to a substantial decrease of the sorption rate.
