Adsorption of gas mixtures on heterogeneous surfaces. Analytical solution of integral equation for jovanovic adsorption isotherm

Abstract

New adsorption isotherms for binary gas mixtures on heterogeneous surfaces have been obtained by using the generalized integral equation for the overall adsorption isotherm. The isotherms have been derived from certain arbitrary but solvable energy distribution functions if the Jovanovic mixed isotherm represents the individual homotattic sites. From mathematical analysis of the generalized integral equation, it follows that the mixed Jovanovic equation used as the local adsorption isotherm is most convenient with regard to analytical and numerical calculations.
