    Chemical Heterogeneity of Metal Oxide Surfaces as Studied by Inverse Gas Chromatography at Finite Concentrations by V.I. Bogillo, V.P. Shkilev, A. Voelkel

    Published 1996-06-01
    “…A method for the calculation of the heterogeneous solid surface distribution function on the adsorption (free adsorption) energy as the sum of two uniform functions and on parameters describing the donor–acceptor and dispersive properties of the adsorption sites direct from chromatographic peaks as measured by inverse gas chromatography of ‘test ’ adsorbates at finite concentrations has been proposed. …”
