The values of the specific retention volumes of non-polar and polar adsorbates chromatographed on the ordered mesoporous silica adsorbents (MCMs) were determined under their infinite dilution conditions. Two methods were employed for the calculation of the standard free energy of adsorption, ΔGads, of the chromatographed adsorbates on the basis of the specific retention volumes. The ΔGads values were employed for the estimation of the van der Waals contribution and specific contribution of the free surface energy for the MCMs and the parameters characterising their ability to act as acceptors, KA, and donors, KD, of electrons.
