“…As demonstrated in [24], thermodynamic treatment can yield reliable information about adsorption behavior even in the case of direct experimental data not being available. According to the method suggested for the calculation of adsorption excesses from surface tensions [24], the binary and ternary adsorption excesses of the cyclohexane/benzene/nhexane mixture were calculated from data as predicted by Eq.…”

The utilization of excess quantities as the basis of a thermodynamic approach can simplify the prediction of multicomponent data from binary ones. Whereas in Part II the excess formalism was applied to the prediction of liquid phase adsorption on solids, in this paper, the liquid/air interface is investigated. In order to show the generality of the suggested approach, thermodynamic equations are developed in analogy to Part II. Surface tensions are predicted by different excess models and compared with experimental data. From predicted surface tensions, ternary adsorption isotherms on the liquid/air interface are calculated.

“…The adsorption excess Γ σ k of the ith component, related to the surface of the mixture, can, however, be calculated from surface tension data. The thermodynamic equations as derived in [24] were used for the calculations of adsorption excesses from predicted ternary surface tension data.…”

“…Figure 6 gives an example of ternary adsorption excesses at the liquid/air interface as calculated from experimental surface tensions. The ideal and real adsorption excesses of n-propanol from the ternary npropanol/ethylene glycole/water mixture are shown (Kalies et al, 2002). Ideal excesses are calculated without considering activity coefficients.…”

“…Theory can help to reduce the number of necessary measurements of adsorption excesses for ternary or higher-order liquid mixtures. Up to now, the international standard of thermodynamic methods for predicting multicomponent adsorption on solids from binary data has been based on models applying absolute quantities (Larionov and Myers, 1971;Minka and Myers, 1973;Price and Danner, 1987;Myers et al, 1987;Price and Danner, 1988;Myers, 1991;Kalies et al, 2002).…”

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.
