Abstract
The mixed micelles C12E4 (tetraethylene glycol mono-n-dodecyl ether)/CTAB ( hexadecyltrimethylammonium bromide) were studied. The surface tension resul ts were analyzed on the basis of a treatment that considers the relation be tween the activity coefficients according to the Gibbs-Duhem equation. The results are compared with Rubingh's treatment, which considers the activity coefficients given by the regular solution theory. The conductivity of the samples and the aggregation numbers at low mixture concentration are also given.
