    Description / Table of Contents: Zusammenfassung Die Konkurrenzadsorption von Multikomponenten-Mischungen von Nichtelektrolyten an energetisch heterogenen Festkörpern wird im Rahmen der Statistischen Thermodynamik beschrieben. Die Integralgleichungen für fundamentale thermodynamische Größen, die Konkurrenzadsorption an der Festkörper — Flüssigkeit Phasengrenze charakterisieren, sind ausgeführt. Es wurden extensive Modelluntersuchungen zur Illustration des Einflußes der Heterogenität der Adsorbenten auf das Verhalten dieser thermodynamischen Größen durchgeführt.
    Notes: Summary A simple model for competitive adsorption from multicomponent non-electrolytic liquid mixtures on energetically heterogeneous solid surfaces is discussed in terms of statistical thermodynamics. Integral equations are derived for the fundamental thermodynamic quantities that characterize competitive adsorption at the liquid-solid interface. Extensive model studies are presented in order to illustrate the influence of adsorbent heterogeneity on the behaviour of these thermodynamic quantities.

    Thin-layer adsorption chromatography with mixed mobile phases. 4. Extension of Ościk's equation to heterogeneous adsorbents (1981)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 4 (1981), S. 17-23 
    Details
    ISSN: 0935-6304
    Keywords: Thin-layer chromatography, TLC ; Liquid chromatography, LC ; Adsorption chromatography ; LC with mixed mobile phases ; Heterogeneity effects in adsorption chromatography ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: In this paper the equation for thin-layer adsorption chromatography with multicomponent mobile phases, proposed by Ościk in 1965 is extended to energetically heterogeneous solid surfaces. Other forms of this equation, more convenient in practical applications, are presented. Model calculations are made for TLC with binary mobile phases according to the modified form of Ościk's equation. Finally, this equation is compared with that of Snyder.
