Abstract
The traditional version of the theory of volume filling of micropores was used for the estimation of the fractal dimension of microporous solids. For this purpose, the Dubinin’s integral equation was solved for infinite and limited integration limits. The results were applied to the adsorption of nitrogen ( T = 78 K) on coal samples and Davisil F silica and to the adsorption of water ( Т = 293 К) on lunar soil sample and on rice starch.
