ADSORPTION AND MOBILITY OF MOLECULES OF WATER AND ORGANIC-COMPOUNDS IN CARBON ADSORBENTS .6. MOBILITY OF MOLECULES OF WATER AND ORGANIC-COMPOUNDS ADSORBED IN A MIXTURE ON ACTIVE CARBONS

The mobility of molecules of water and fluorine-containing organic com pounds adsorbed in a mixture on active carbons has been studied by the NMR pulsed field gradient technique (H-1 and F-19 resonances). Sample s with various H2O/C6F6 and H2O/C2Cl3F3 ratios have been examined. The mobility of components at total fill factors theta > 0.8 has been sho wn to decrease in comparison with the adsorption of pure substances wh ile the diffusion activation energy increases. The results are interpr eted on the basis of adsorption mechanisms of water and organic compou nds on active carbons.
