Activity Coefficients at Infinite Dilution from Surface Tension Data

摘要: A method for calculating activity coefficients at infinite dilution from surface tension data is derived the conditions equilibrium between and bulk phases rather than liquid-vaporor liquid-liquid equilibrium, as more usual. Specifically, combines Volmer equation of state Gibbs adsorption to derive an expression chemical potential. The key operation this treatment choice same reference both phases. γ ∞ values calculated systems which suitable are available in literature agree well with obtained by other methods.
