| Abstract: | The substantiation and the area of applicability of the Dubinin—Radushkevich equation for determination of the micropore volume
in microporous systems from experimental data on adsorption isotherms were examined. It was shown that the micropore volumes
found using the standard procedure are overestimated. A more accurate method for determining the mircopore volumes based on
the pressure of filling of micropores was proposed.
