Abstract

Adsorption of water molecules by clinoptilolite and glauconite was studies by isopiestic method within a wide range of water activity. A quantitative assessment of hydration properties of sorbents was given. The regularities of water adsorption caused by the structural features of the sorbents were determined and explained. The adsorption theory of Brunauer, Emmett and Teller (BET) was applied for description of water adsorption by aluminosilicates. It was shown that the first monomolecular layer of the adsrobate is formed due to interaction of water molecules with extra framework cations and electronegative sites of sorbent framework.
