Polymer surfactant interactions: Surface tension, conductance and spectrofluorometric studies
Author(s): Praveen Kumar and Sachin Kumari
Abstract: Surface tension and electrical conductivity data have been measured for aqueous solution of anionic [bis (2-Ethylhexyl) sulphosuccinate sodium salt (AOT)], cationic [cetyl trimethyl ammonium bromide (CTAB)] and non-ionic [polyethylene (23) lauryl ether (Brij-35)] surfactants with inulin (carbohydrate polymer) at 298.15, 308.15 and 318.15 K temperature. The observed data has been utilized to evaluate the critical micelle concentration (CMC), counter-ion association (β), surface excess concentration (G), minimum area per molecule (Amin), surface pressure at CMC (pCMC), thermodynamic properties of micellization (rGºmic, rHºmic, rSºmic) and adsorption (rGºads, rHºads and rSºads). Intermolecular interactions of inulin-surfactant mixture in water were also studied spectrofluorometrically using pyrene as a fluorescence probe.
