### Abstract

A non-graphical solution of the Gibbs adsorption isotherm equation is proposed for solid-binary liquid systems which obey the Everett-Schay function. The composition dependence of the bulk activity is represented by the n parametric Redlich-Kister equation. The interfacial tension σ is then expressed as a function of the mole fraction x_{1} according to σ(x_{1}) = σ^{0}
_{2} + J ln (1 + Kx_{1})+ {A figure is presented}L_{j}x^{j+1}
_{1}. A physical meaning is assigned to each parameter σ^{0}
_{2}, J, K, L_{j}. The application of the equation derived is presented for several solid-binary liquid systems and the dependence of the results on the reliability of the activity data is considered. The method can also be applied to liquid-vapour interfaces.

N2 - A non-graphical solution of the Gibbs adsorption isotherm equation is proposed for solid-binary liquid systems which obey the Everett-Schay function. The composition dependence of the bulk activity is represented by the n parametric Redlich-Kister equation. The interfacial tension σ is then expressed as a function of the mole fraction x1 according to σ(x1) = σ0 2 + J ln (1 + Kx1)+ {A figure is presented}Ljxj+1 1. A physical meaning is assigned to each parameter σ0 2, J, K, Lj. The application of the equation derived is presented for several solid-binary liquid systems and the dependence of the results on the reliability of the activity data is considered. The method can also be applied to liquid-vapour interfaces.
