Calculation and prediction of adsorption excesses on the ternary liquid mixture/air interface from surface tension measurements

J Colloid Interface Sci. 2002 Mar 1;247(1):1-11. doi: 10.1006/jcis.2001.8108.

Abstract

The surface tensions of the n-propanol/ethylene glycol/water ternary mixture and its binary mixtures are measured at 293 K and described by mathematical functions. The experimental data and their descriptions are shown in the three-dimensional space by means of coordinate transformation. A thermodynamic model to calculate and predict ternary adsorption excess data on the ternary liquid mixture/air interface from surface tensions is presented. The calculated adsorption excess data in the ternary triangle are discussed.
