Prediction of Ternary Liquid Adsorption on Solids from Binary Data

Prediction of multicomponent liquid adsorption using excess quantities

“…Equilibrium constants for the quasi-chemical reactions have been formulated [7]. Our calculations have shown that those methods of prediction yield good qualitative results, whereas the quantitative correspondence between ternary predictions and measured data is insufficient for nonideal adsorption systems [10,11].…”

Prediction of multicomponent liquid adsorption using excess quantities

“…The adsorption data predicted by the suggested model are discussed and compared with experimental data and with those of other models in the literature [1,3,7]. Although the number of published ternary adsorption systems studied over the entire concentration range is growing [8][9][10][11][12][13], complete tabular sets of liquid adsorption data for a ternary mixture and its constituent binary mixtures data are rare in the literature.…”

“…So far, the international standard of thermodynamic methods for predicting multicomponent adsorption from binary data has been based on models applying absolute quantities [1][2][3][4][5][6][7]. In liquid-phase adsorption, only excess quantities can be measured, which makes it hard to understand why existing theories for the prediction of multicomponent data from binary data are all based on absolute quantities.…”
