The adsorption of ammonia on sodium forms of A, X and Y type synthetic zeolites and mordenite are examined in the 423-573 K temperature interval in a flow apparatus using helium as carrier gas. Diffusion controlled penetration of ammonia into the sodalite cage, most marked for Y type zeolites, is fo
