Résumé :

From variation of surface tension with temperature of aqueous solutions of surfactants, the heat of reversible adsorption at constant temperature and surfactant mole fraction in the bulk can be calculated on a thermodynamic basis. Therefore, the Gibbs adsorption equation is rearranged in a suitable form, where the coefficient of dT does not depend on the choice of the standard entropy. © 1973.
