  • Abstract

    Ultrasonic velocity, density and viscosity of different concentrations of aqueous solutions of dimethyl sulfoxide (DMSO) and acetonitrile (ACN) have been studied at 298.15 K. From the experimental data various acoustical parameters such as Free volume Vf, Relaxation time τ, Gibb’s free energy ΔG, Absorption coefficient α/f2 have been evaluated. Also hydrodynamic flow studies of different concentrations of experimental solvents through commercially available AcroshieldTM H 69008 composite cellophane membrane are described and used to evaluate transport properties such as permeability coefficient Lp and frictional coefficient Fwm. The acoustical parameters of different concentrations of aqueous solutions of DMSO and ACN were correlated with their transport properties. The results are discussed in the light of intermolecular interactions occurring in the solutions and also in terms of interactions between membrane and solution.
