Abstract
The physicochemical and interfacial properties of the monomeric surfactants cetyltrimethyl ammonium bromide (CTAB), cetyltriphenyl phosphonium bromide (CTPB), tetradecyl triphenyl phosphonium bromide (TTPB), cetyldiethylethanol ammonium bromide (CDEEAB), cetyltrimethyl ammonium chloride (CTACl), tetradecyltrimethyl ammonium bromide (TTAB), and a gemini surfactant (C16-3-C16, 2Br−) at different pH (3.1, 7.0, and 7.75) have been investigated by conductivity and surface tension measurements at 300 K. The critical micellar concentration (CMC), degree of micellar ionization (α), surface excess concentration (Гmax), minimum surface area per molecule of surfactant (A min), Gibbs free energy of micellization (∆G 0m ), surface pressure at the CMC (π CMC), and the Gibbs energy of adsorption (∆G 0ads ) of the monomeric surfactants have also been determined. The CMC, α and Гmax, increase with increasing pH whereas A min decreases.
