Abstract

Changes that occur in the surface properties and porous structure of montmorillonite upon the substitution of its exchange cations by polyhydroxyaluminum cations are studied. Preliminary thermovacuum treatment noticeably affects the adsorption properties of polyhydroxyaluminum montmorillonite with respect to methanol. The dependences of the adsorption heat on the amount of adsorbed methanol are established based on a set of isosteres of CH3OH adsorption on dehydrated sodium and modified montmorillonites measured in a wide temperature range.
