New BET type multilayer sorption isotherms. Part I: Theoretical derivation of the model

Based on the hypothesis that the heat of sorption for the second and higher adsorbed layers increase, decrease or remain constant, taking as limit the heat of evaporation-condensation, a group of BET-type multilayer isotherms has been derived. In the first and second cases it was found that the isot...

Based on the hypothesis that the heat of sorption for the second and higher adsorbed layers increase, decrease or remain constant, taking as limit the heat of evaporation-condensation, a group of BET-type multilayer isotherms has been derived. In the first and second cases it was found that the isotherms derived predict that the amount adsorbed for a given water activity, is respectively lower or higher than that corresponding to BET equation. Both isotherms showed infinite sorption at X = 1 as BET equation. It was also demonstrated that when the heat of sorption is assumed constant for all adsorbed layers above the first, the isotherm obtained is the GAB equation. © 1989 Academic Press Limited.
