摘要：

Effects of the oxidation with nitric acid of active carbons from different origins have been studied by inverse gas chromatography. It is shown that the oxidation of activated carbons with nitric acid increases their acidity considerably, and at the same time decreases their adsorption affinity for n-alkanes, which is manifested by the decrease of the dispersive component of surface energy, gamma(s)D, and adsorption enthalpies of alkanes. A correlation has been established between the acidity of carbons measured by base titration and the energy of the specific interactions with pi-bonds of unsaturated hydrocarbons.
