摘要: The new theoretical approach to multisite-occupancy adsorption on heterogeneous surfaces, developed recently by Rudzinski and Everett, is generalized for the case of systems characterized non-Gaussian energy distributions. Attention focused distribution which, in one-site -occupancy adsorption, leads Dubinin-Astakhov isotherm equation. In effect, a form that equation common actual systems. sensitive surface topography; hence, fitting it experimental isotherms creates chance study topography carbonaceous surfaces. An example such computer exercises reported here before more systematic published.
