Dubinin and the Brouers-Sotolongo family isotherms

Abstract

We show how the Dubinin isotherm and its extensions can be related to the isotherms derived from the general BrouersSotolongo isotherm. We compare them using benzene vapor adsorbed on activated carbon data from one of the original Dubinin paper. We use the same procedure to analyze data from the thesis of MarquezMontesino on the adsorption on activated carbon prepared from pinus caribaea saw dust. We conclude by proposing a simple methodology to determine the macroscopic information given by genuine statistical isotherms.
