Adsorption Layers

Adsorption at the gas —air interface and micelle formation in binary solutions of ethoxylated alkyl phenol (Neonol AF 9-10) and sodium oleate have been studied. The Rubin and Rosen equations were used to determine the interaction parameters and the composition of mixed micelles and adsorption layers depending on the initial solution composition. The authors have found out that the micelles and the adsorption layer at the interface are enriched in a non-ionic component. The maximum synergistic effect during micelle formation was found for solutions containing 20–30 % molar of reagent Neonol AF 9-10, and during adsorption —20 and 50 %.

Surfactant Micelles

Kinetic studies through stopped-flow spectroscopy were undertaken in the dilute solution range of anionic surfactants where pronounced rate enhancement or inhibition of Ni2+-ligand complexations is often observed at surfactant concentrations much below the critical micelle concentration (CMC). The results are interpreted in terms of Ni-surfactant micelles as the agents responsible for the rate changes in dilute surfactant solution. At higher surfactant concentrations these micelles are transformed into mixed micelles (counterion and size changes), eventually becoming normal surfactant micelles close to the CMC. Surface tension, dye solubility, conductivity, and fluorescent probe investigations support this interpretation.Key words: micellar catalysis, sodium dodecyl sulfate, micelles, critical micelle concentration, premicelles, Ni2+-ligand complexations.

Cationic And Anionic Surfactants

Interactions taking place in aqueous solutions when cationic surfactants, alkyl trimethyl ammonium bromides (CnTABs, dodecyl or octadecyl), are added to solutions of anionic surfactants, like alkyl dithiocarbonates (xanthates, hexyl or nonyl) and dodecyl sulfate or laurate ions, result either in the formation of 1:1 complexes or in mixed micelles. Infrared and ultraviolet spectra show that complexes are largely ionic, with some perturbations of bonds in anions and a limited hydrolysis in the case of laurate ions.
