Dubinin's Theory for the Volume Filling of Micropores: An Historical Approach

The origin and development of Dubinin's theory are presented within their historical context. The emphasis is put on the author's long-standing collaboration with M.M. Dubinin. It is shown how the main correlations between the structural properties of active carbons and the parameters of the DR and DA equations have been established and crosschecked. As shown recently, the adsorption of water by microporous carbons, corresponding to a type V isotherm, can also be described by the equation of Dubinin and Astakhov. This new approach includes the enthalpy of immersion into water, a thermodynamic consequence of Dubinin's theory.
