Summary

A method is described for calculating the surface tensions of solutions containing binary mixtures of surfactants which exhibit non-ideal surface mixing behaviour. The method, which utilizes a regular solution model for suface and micellar mixing, has been used to predict the surface tension concentration curves for a mixture of ionic and nonionic surfactants.

Zusammenfassung

Es wird eine Methode beschrieben zur Berechnung der Oberflächenspannung von Lösungen, die binäre Mischungen von Tensiden enthalten, welche ein nichtideales Oberflächenmischungsverhalten aufweisen. Die Methode, die ein Modell für reguläre Lösungen von oberflächlichen und mizellaren Mischungen benutzt, wurde verwendet zur Vorhersage der Oberflächenspannungs-Konzentrations-Kurven für eine Mischung, bestehend aus ionischen und nichtionischen Tensiden.
