Abstract

The differential isosteric heat of adsorption of pyridine vapors on dehydrated sodium and
polyhydroxialuminium form montmorillonites were determined. The temperature dependence of
adsorption equilibrium parametrеs shown that the substitution of [Al13O4(OH)24(H2O)12]7+ for
exchangeable cations of montmorillonite causes an increase in the volume of the micropores and in the
heat adsorption.
