摘要：

The mobility of molecules of water and fluorine-containing organic compounds adsorbed in a mixture on active carbons has been studied by the NMR pulsed field gradient technique (H-1 and F-19 resonances). Samples with various H2O/C6F6 and H2O/C2Cl3F3 ratios have been examined. The mobility of components at total fill factors theta > 0.8 has been shown to decrease in comparison with the adsorption of pure substances while the diffusion activation energy increases. The results are interpreted on the basis of adsorption mechanisms of water and organic compounds on active carbons.
