DEPENDENCE OF THE DISTRIBUTION COEFFICIENT ON THE MOBILE PHASE-COMPOSITION IN LIQUID ADSORPTION CHROMATOGRAPHY .2. ANALYTICAL EQUATIONS FOR THE DISTRIBUTION COEFFICIENT INVOLVING NON-IDEALITY OF THE MOBILE PHASE AND HETEROGENEITY OF THE ADSORBENT SURFACE

This paper deals with theoretical studies on the effects of adsorbent heterogeneity in liquid adsorption chromatography with a two-component non-ideal mobile phase. Equations for the distribution coefficient, taking into account the adsorbent heterogeneity and non-ideality of the mobile phase, are derived in terms of the treatment presented in a previous paper [1]. Extensive model calculations are presented for the distribution coefficient using different values of the parameters characterizing non-ideality of a binary mobile phase and energetic heterogeneity of adsorbent surface. © 1979 Friedr.
