Abstract

A new version of the regressive technique is proposed for calculating adsorption parameters from two-dimensional pressure isotherms. The method assumes that the Frumkin isotherm is applicable to individual adsorption of surface-active neutral molecules and single-charged ions. Based on literature data, the adsorption parameters are assessed for tetraethylammonium, tetrapropylammonium, and tetrabutylammonium cations and for saccharose molecules for their adsorption from aqueous solutions on the uncharged mercury surface.
