Abstract

Based of numerical calculations, it is shown that for two organic substances with similar dependences of adsorption on the electrode potential, the overall surface coverage is well described by the ordinary Frumkin isotherm with a certain effective attraction constant a eff. A correlation between the a eff value and the constants of intermolecular interaction in the adsorption layer was revealed for co-adsorbing molecules 1 and 2, namely, a 11, a 22, and a 12.
