Abstract

The kinetics of Sr2+ ion-exchange process on NH4+-forms of clinoptilolites from deposits in Russia and Bulgaria on the sample of the surface drinking water was investigated in detail. It was shown, that the kinetic process on clinoptilolite includes 3 stages. The obtained data are the initial one for the development of a mathematical model of the dynamic ion-exchange process on NH4+-form of clinoptilolites from diluted solutions that makes possible to generate the computer program and thereupon to calculate the break-through curves of Sr2+ sorption on NH4+-clinoptilolite for different dynamic conditions.
