ADSORPTION PROPERTIES AND POROUS STRUCTURE OF NEW CARBON MATERIALS

The adsorption properties of the new carbon materials, sibunites, whic h are mesoporous samples with a developed surface of pores, were studi ed. The isotherms of the adsorption of benzene vapor were determined t o estimate the porous structure of these materials. The principal meth ods for calculating the parameters of the porous structure of sibunite s were analyzed. The application of the BET equation even in the prese nce of a small number of micropores can distort the results, therefore the most suitable method for estimating the surface of mesopores is o ne that is based on the Dubinin-Zaverina equation. The estimation of t he surface of sibunites using water vapor adsorption is demonstrated.
