Abstract

The process of adsorption of strontium ions on the modified layered aluminosilicate – montmorillonite
was studied in the paper. The thermodynamic parameters of the adsorption were calculated. The investigations
were carried out on the model solutions of stable strontium.
By modifying montmorillonite surface it was established a significant increase of its adsorption capacity.
The parameters of the Gibbs energy such as ∆G, ∆H, T × ∆S were determined. Received and investigated
adsorbents can be used for the deactivation of water containing radionuclides Sr90.
