Abstract

Results are analyzed of the study of the Adsorption and Differential Isosteric Heats of Adsorption of
Carbon Tetrachloride on Polyhydroxyaluminum Montmorillonite dehydrated in the interval 293-873K.
Isotherms of adsorption were measured at sorption plant with quartz spring balances similar to Mak-Ben’s,
but isosters – on volumes plant for direct measure of adsorption of isosters. Formation of chinkous
micropores upon substitution of cations of sodium on polyhydroxyaluminum leads to rapid increase of
adsorption the volume of minerals and the increase of thermostability. Dependence of heat adsorption of size
of adsorption has extreme character. Heat adsorption of CCl4 on PHAM dehydrated at 423 K was much more
than the sample dehydrated at 873 K.
