Adsorption of argon on alumina and calculation of the adsorption potential

Abstract

The adsorption of argon on hydroxylated γ-alumina that had been subjected to various thermal treatments in order to dehydrate it, has been studied by means of experimental adsorption isotherms at different temperatures. The experimental adsorption energy, determined macroscopically from the heat curve or from the B.E.T. model, was interpreted at the molecular level by calculating the adsorption potential using for the distribution of the solid's force centre a model based on Peri's classical two-dimensional model for the surface of alumina.
