✦ Synopsis

It is considered that one requirement (among others) for the Dubinin equation to linearise adsorption isotherms of carbons is the forces of adsorption should be essentially non-polar, Van der Waals forces. To test this assumption molecules with permanent dipoles, e.g. NH3 and H2S have been adsorbed on selected carbons. Although linear Dubinin plots can be obtained, the temperature dependence is without meaning and the Dubinin equation cannot be used to predict micropore volume.
