Adsorption from binary liquid mixtures on chromatographic silica gel

Abstract

Adsorption equilibria of binary solutions of cyclohexane, benzene and dioxane on chromatographic silica gel at 20°C have been determined. The thermodynamic treatment outlined by Everett and by Schay and Nagy have been applied. The results obtained by the alternate methods show a fair agreement in the n^σ/m and x^σ _i values, but differences are observed in the log f^σ _i values.
