The adsorption behavior of various organic compounds at bismuth, antimony, cadmium, mercury and other "mercury-like" metals has been discussed. The systematic trends of the influence of the chemical nature of electrode metal and adsorbate to the molecular interaction parameter, alpha; limiting Gibbs adsorption, Gamma(A, max); and Gibbs energy of adsorption, Delta G(A)(O), have been analyzed. The ingredients of the total Gibbs energy of organic compound adsorption have been found. A new more general method for obtaining the metal-water interaction Gibbs energy has been worked out and used. It was found that the dependence of Gibbs energy of metal-water interaction on the chemical nature of metal and aliphatic organic compound studied is weak. Only in the case of chemically very different metals, for example for Sb and Zn, the difference of Gibbs energy of metal-water interaction values is somewhat higher than the exactness of the determination of the experimental values of Gibbs energy of organic compound adsorption.
