Interaction of Ethanol Vapour with Silane-Modified Surface of Corning Porous Glass CPG-10
Figure 4
Showing type IV ethanol adsorption isotherm (millimoles per gram versus ) on DMDCS-modified CPG-10. A clear type H1 hysteresis is obtained in this case from type H3 of the unmodified sample (Figure 1). The hysteresis loop shifts to the lower pressure end () and is more asymptotic to the saturation axis ().
