Abstract

The acoustical parameters of glycine have been measured in aqueous solutions of surfactants, such as sodium cetrimide, sodium dodecylsulphate(SDS), and Triton-X(100) (TX-100) at 298.15K. The molar sound velocity (R), molar compressibility (W), free length (Lf), free volume (Vf), internal pressure (πi), relaxation time (τ), ultrasonic attenuation (α/f2), and van der Waals constant (b) values have been calculated from the experimental data. These parameters are used to discuss the molecular interactions in the solutions.
