“…As different from previous models applying absolute quantities, the new approach is based exclusively on binary excess data and independent of assumptions for the Gibbs surface phase model. Qualitative and quantitative agreement between theory and experiment was obtained for different near-ideal and non-ideal ternary adsorption systems (Kalies et al, 2004b(Kalies et al, , 2004c. In addition, the application of excess formalism allows the calculation of immersion quantities (Kalies et al, 2005).…”

“…(1). The predicted data are compared with consistent sets of experimental data (Minka and Myers, 1973;Kalies et al, 2004b). Qualitative and quantitative agreement between theory and experiment is obtained for the near-ideal n-hexane/n-octane/ntetradecane ternary mixture on Carboxen 563 at 298 K as well as for the non-ideal cyclohexane/ethyl acetate/benzene ternary mixture on activated carbon at 303 K.…”

“…Since the binary specific free wetting energies can be obtained from measured binary adsorption excesses and from the bulk activity coefficients of component j in the binary mixture, Eq. (1) can be used for predicting ternary specific free wetting energies and thus for predicting the ternary adsorption excesses σ k , which are related to the mass of adsorbent (Kalies et al, 2004b). The excess parts of the binary and ternary specific free wetting energies can, for example, be described by Redlich-Kister polynomials.…”

Thermodynamic equations for the description of multicomponent liquid adsorption equilibria on solids are often formulated in terms of absolute quantities instead of excess quantities. Considering the excess nature of liquid adsorption phenomena, the utilization of excess quantities seems to be more suitable for the analysis and prediction of multicomponent liquid adsorption. In this paper, a brief summary of four different possible applications of adsorption excess formalism is given. Calculations and experimental data are used to illustrate theoretical relations and to demonstrate their applicability.
