Study of kinetic curves of sorption of Ca2+ and  Mg2+ ions in Na-clinoptilolite shows that for both of ions-exchange reaction occurs in mixed diffusion area. In the first stage sorption process goes on by external  diffusion mechanism with a majority of ions, but in the second stage the process of sorption proceeds by internal diffusion mechanism.
