Acoustical and transport behavior of some amino acids in aqueous DMSO solutions at 303.15K

摘要

Ultrasonic velocity (U), Viscosity (η) and density (ρ) have been measured for three amino acids viz., L-glutamine, L-arginine, L-lysine in aqueous DMSO solutions at 303.15K. Using the experimental values, the adiabatic compressibility (β), hydration number ( H n ), apparent molar compresiblility ( K j ) apparent molar volume ( V j ), limiting apparent molar compressibility ( 0 K j ), limiting apparent molar volume ( 0 V j ) and their constants ( K S , V S ), transfer volume ( 0 VDj ) and viscosity A and B coefficients of Jones-Dole equation were calculated. The experimental results have been discussed in terms of ion-solvent and solute–co-solute interactions on the basis of cosphere over lap model.
