ABSTRACT

In this paper, we examine density (d), ultrasonic velocity (u) and viscosity studies of SDBS and DTAB in water and in aqueous solutions of (0.01, 0.05, 0.10) mol*kg-1 L-glutamine, L-histidine and L-methionine at T = (293.15, 298.15, 303.15, 308.15, 313.15) K. The apparent molar volume ( ) dependence on SDBS and DTAB concentration reflects the modification of water-water interactions described as hydrophobic hydration of the surfactant molecules in the presence of amino acid. The trends of apparent molar adiabatic compression ( ) values of DTAB with surfactant concentration appears reasonable to suggest that hydrophilic hydration of DTAB-amino acid complex occurs at low surfactant concentration region rendering it to be negative. The gradual increase in viscous relaxation time ( ) with rise in concentration of surfactant and decrease with temperature seems to be happen due to the structural relaxation processes occurring as a result of re-arrangement of molecules.
