Acoustic and aggregation properties of sodium dodecyl sulfate in aqueous amino acid systems have been studied through ultrasonic velocity techniques at different temperature as a function of concentration and at different temperature (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15 K) and atmospheric pressure using density and sound velocity analyzer (DSA 5000, Anton paar, Austria). Densities and ultrasonic velocity of sodium dodecyl sulfate in aqueous amino acid have been measured and from the experimental data, adiabatic compressibility (βS), apparent molar adiabatic compressibility (φk), critical micelle concentration (CMC), acoustic impedance (Z), relative association (RA) and molar sound velocity (Rm) have been calculated. The results show significant information about acoustic properties of sodium dodecyl sulfate (solute-solute interactions, aggregation behaviour, relative association and structure formation) in aqueous and aqueous amino acid solution.
