Theory of the Volume Filling

Benzene was the most popular adsorptive in many early studies of the pore structure of activated carbons (Dubinin, 1958,1966 Cadenhead and Everett, 1958 Smisek and Cemy, 1970). Indeed, in order to construct the characteristic curve for a given micro-porous carbon, Dubinin and his co-workers (Dubinin, 1966) originally adopted benzene as the standard adsorptive thus, in the context of the Dubinin theory of the volume filling of micropores (TVFM), the scaling factor p (C6H6) = 1 (see Chapter 8).

In order to characterize the adsorbents micropore syston we used the Dubinin theory of the volume filling of micropores. The isotherm for sUt-shaped micropores of activated carbon was described by the Dubinin-Asthakov (DA) equation in the relative pressure range 10 -0.2 [5] ...
