The N 2 and O 2 sorption was studied on synthetic and natural mordenites, and on molecular sieves 4A, 5A and 13X. The sorption dynamics was characterized by frequency response rate spectra, determined at 133 Pa, 195 or 298 K. The rate of sorption step governed the mass transport in all powder sample
