Adsorption characteristic of Mg2+ form of the zeolite 4A

Abstract

The first experimental works for adsorption of gases on zeolites and the influence of molecular-sieve properties was made on natural materials by F. Gradian who studied adsorption of gases on dehydratited zeolites. The ability of adsorption properties of the zeolites is determined by two factors, character of the porous structure and the heteropolar character of the polar centers. In our research adsorption is determined with water vapor by a static-gravimetric method. The results are presented in tables and graphic dependence is represented by adsorption isotherms in Langmuir 's coordinates.
