Abstract
In the present study, multilayer gas adsorption on the heterogeneous solid surface has been studied. By considering the heterogeneity of solid surface, a new isotherm for studying multilayer adsorption has been derived. By the use of some assumptions, a new equation for multilayer adsorption on heterogeneous solid surface has been derived. The new isotherm has been analyzed by some of the experimental data of multilayer adsorption at solid/ gas interface. A comparison between the new equation and BET isotherm has been provided. The results showed that the new equation has a good conformity with experimental data. It was shown that the new isotherm has more applicability in comparison with BET isotherm.
