Popis: | SBA-16 silica samples with cubic I m 3 ¯ m symmetry were synthesized according to methods reported in literature and characterized by nitrogen adsorption and X-ray diffraction. The adsorption behavior of the n-octane(1)/octanol(2), n-octane(1)/ethanol(3), and octanol(2)/ethanol(3) binary liquid mixtures on SBA-16 was studied over the whole concentration range at 25 °C. Inverted U-shape isotherms were found and described by mathematical functions. The experimental binary data were verified by using a consistency test for the specific free wetting energies on the liquid/solid interface. The ternary adsorption excess isotherms of n-octane(1)/octanol(2)/ethanol(3) at 25 °C were predicted from the binary data. The work presents the first complete and consistent tabular set of binary liquid adsorption data for creating ternary data on ordered mesoporous silica. |
