✦ 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.

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

Data for water adsorption at 293 K by an activated series and a heat-treated series of PVDC based carbons are reported. Type 5 (BDDT) isotherms were obtained for adsorption by each carbon. Total water adsorption volumes (a,) are lower than total pore volumes and Dubinin-Radushkevich micropore volume
