Abstract

Conductivity measurement of dodecyltrimethylammonium bromide in the presence of Brij-35 in aqueous media at 289.15 K is performed. The result showed a sharp increase in conductivity with increase in the concentration of dodecyltrimethylammonium bromide in the presence of Brij-35. The graph of specific conductivity versus concentration is used in determining the critical micelle concentration (CMC). There is the decrease in CMC of  dodecyltrimethylammonium bromide in the presence of  Brij-35 in comparison with the CMC of  dodecyltrimethyl ammonium bromide [DTAB]. Gibbs free energy of micellisation has also been evaluated.
