Abstract

The temperature dependence studies on the binary and ternary system are very few. The densities of sodium dodecyl sulphate (SDS), L-arginine, 2-amino butyric acid in water and SDS mixed with L-arginine and 2-amino butyric acid solutions have been measured precisely at five equidistant temperatures ranging from 293.15K to 313.15K at an interval of 5K. The variety of different thermo- dynamics properties of SDS were observed in the low concentration region. The density of all the studied system was found to increase with the increase of molar concentration of the solution and decrease with the increase of temperature. SDS acts as structure breaker for both regions in aqueous L-arginine and 2-amino butyric acid solvent system at studied temperature.
