Abstract: This paper describes the adsorption of nitrogen and argon on pores in natural mordenites before and after acid leaching treatment. The exchange with H{+} ions during dealumination favors the creation of emergent pores thus causing an increase of the adsorption capacity. The development of nanopores in mordenites was evaluated through the Dubinin-Astakhov and Barrett-Joyner-Halenda methods.
