Effect of Amino Acids on Micellization and Micellar Parameters of Anionic Surfactant Alpha Olefin Sulfonate C14–C16 in Aqueous Solutions: Surface Tension, Conductometric, Volumetric, and Fluorescence Studies

The effect of l -glycine, l -alanine, and l -leucine on micellization, surface activity, and colloidal parameters of an anionic surfactant sodium alpha olefin sulfonate C 14 –C 16 in aqueous solutions at different temperatures was studied. It was shown that the hydrophobicity of the studied amino acids had great influence on behavior of physicochemical parameters. In studied systems, the electrostatic interactions between zwitterionic groups of amino acids and ions of sodium alpha olefin sulfonate C 14 –C 16 were also important.
