摘要

The new correlations recently suggested between the properties of the carbon surface and the constants characterizing the process of aeelanilide adsorption were extended from data that had been measured initially for six carbons. It was shown that the mechanism of aeetanilide adsorption on carbons was mixed between micropore filling and adsorption on active surface sites. The latter depended strongly on the concentration of surface earhoxylie, phenol and basic groups. In acidic pH, the process was irreversible due to the chemisorption of acetanilide molecules on the nucleophilic carbon sites. The rate of adsorption of aeelanilide increased at acidic pH levels. Diffusion was mainly a surface process with the energy of diffusion depending on the chemical composition of the carbon surface and its polarity.
