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

A discussion is given of the various anomalies apparent in the literature since the publication of the Fuoss-Onsager conductance equation in 1957. A careful re-analysis of available conductance data leads to a reconsideration of the physical meaning of the distance parameter in agreement with Bjemun
Decreases in the characteristic energy of the Dubinin-Radushkevich equation, E,,, are correlated with increases in micropore sizes determined by molecular probes, W,,,, using the empirical equation W, = 4.691 exp( -0.0666&J; a similar equation can also be used to correlate the more limited data rela
