Surfactant Solutions

Viscosity measurements have been made to the solutions of dodecyltrimethylammonium bromide (DTAB) and cetyltrimethylammonium bromide (CTAB) in 0.10, 0.20, 0.30, and 0.40 volume fractions of methanol in methanol-water mixed solvent media at 298.15, 308.15, 318.15, and 323.25 K. Critical micelle concentration (CMC) values have been determined. From relative viscosity for surfactant solutions, related viscosityBcoefficients are calculated and the values are interpreted in terms of solute-solvent interactions.

Solubilization of the drug diclofenac sodium (DS) in micellar aggregates of ionic liquid-based surfactants and cetyltrimethylammonium bromide at 25 °C induces changes to worm-like micelles and vesicles, with potential use in drug delivery.

Sonochemical Reduction

Gold seed particles stabilized by citric acid were prepared by the sonochemical reduction of Au(iii) ions in aqueous solutions. These seed particles were grown by the reduction of adsorbed Au(iii) ions by ascorbic acid in aqueous solutions containing cationic surfactants, dodecyltrimethylammonium bromide (C12TAB), hexadecyltrimethylammonium bromide (C16TAB) and didodecyldimethylammonium bromide (DDDAB). The rate of reduction of Au(iii) ions during the seed-growth process was found to be strongly dependent upon the type and concentration of the cationic surfactants. The presence of Ag(i) in the growth solution containing DDDAB affected the size distribution of the gold particles.
