Summary

  1. 1.

    The effect of energetic inhomogeneity of the surface on the character of the dynamic desorption curves in chromatographic analysis has been analyzed.

  2. 2.

    The relation between the form of desorption curvesc =c(V) and the form of the function expressing the distribution with respect to their heats of adsorption of sites on the surface ρ(Q) has been obtained.

  3. 3.

    A method is given for the construction of ρ(Q) from desorption curves without having recourse to special adsorption measurements.

  4. 4.

    The equations of desorption curves for the fundamental forms of distribution are obtained.

  5. 5.

    The limits and conditions of applicability of the proposed method are pointed out.
