heal.abstract |
Eight systems namely the C6H6 /Fe2O 3, C6H6/NO2/Fe2O 3, C6H5CH3/Fe2O 3, C6H5CH3/NO2/Fe 2O3, C6H6/ZnO, C6H 6/NO2/ZnO, C6H5CH3/ZnO, C6H5CH3/NO2/ZnO are examined through a version of inverse gas chromatography and six physicochemical adsorption quantities are determined for each heterogeneous system. Thus, the reversed flow-(inverse) gas chromatography is used for the investigation and study of adsorption phenomena taking place on these heterogeneous solid surfaces. In the case of iron oxide the presence of nitrogen dioxide facilitates the chemisorption. This is not obvious in the case of zinc oxide. However, nitrogen dioxide facilitates the adsorption of benzene and toluene through van der Waals forces in both oxides. Through the experimental local quantities determined and the detailed time-resolved analysis, useful information for the nature and the strength of the adsorbate-adsorbent as well as the adsorbate-adsorbate interactions have been extracted giving an insight into the topography of the active sites and the nature of the surface bonds. © 2008 Vieweg+Teubner | GWV Fachverlage GmbH. |
