The porous structure of hard and deformed adsorbents and mobility of adsorbed molecules

The opportunities of pulsed NMR methods for Studying the mobility of adsorbed molecules and porous structure of microporous rigid and non-rigid adsorbents of different nature are considered. The distribution Of nuclear magnetic relaxation times were used to determine the distribution of water and benzene molecules adsorbed in active carbons and in polymer sorbents. The dimensions of the areas corresponding to different porosities have been estimated from the self-diffusion data of water and benzene in AC. The self-diffusion study of water and benzene in the synthetic opals indicate the existence of ultramicropores. The obtained data of nuclear magnetic relaxation and self-diffusion of the adsorbed water and benzene in the different adsorbents are in accordance with the adsorption investigations and complement them.
