“…To perform the multiple derivations, Jagiełło et al have used a virial expansion in order to fit the experimental isotherms. Some examples of distribution functions calculated according to this method are reported in the literature. ,, The high flexibility of this fitting equation, using a limited number of parameters, brings in the well-known default of polynomial fittings, i.e., adding residual oscillations to the experimental data that are greatly amplified by the multiple derivation procedure leading to artifacts …”

The determination of the surface heterogeneity of a solid is a difficult challenge. The present work proposes a method for the determination of the adsorption energy distribution functions (DF) directly computed from the chromatographic signal acquired at finite concentration conditions. The calculation of the DF calls on the extended Rudzinski and Jagiełło's solution method using discrete Fourier transforms to perform the multiple derivation of the distribution function for the condensation approximation. Because of the “ill-posed” character of the fundamental integral equation describing the adsorption on a heterogeneous surface, the good robustness of the method versus the experimental noise and the regularity of the data sampling was evidenced using a simulation program.
