## It is shown that an exact expression can be derived from Dubinin's theory, for the enthalpy of immersion of active carbons. It appears that for a given liquid, the specific enthalpy of immersion is a function of the characteristic energy REo of the Dubinin-Astakhov equation. The new relation is

It is shown that the values of the structural constant B and of the micropore volume W, can change considerably for certain active carbons, when the adsorption of simple gases is measured over a large range of temperature. The changes are probably related to ultramicrop?rosity, present in heterogene
