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 ( ).
