Abstract

Interactions between amino acid (valine) and surfactant (sodium dodecyl sulphate) was investigated using refractive index and conductance data. These data were used to calculate molar refraction (RD), and limiting molar conductance (∧m0) and these parameter further utilized to find out solute-solvent interactions between amino acid and surfactant at 298.15, 303.15, 308.15 and 313.15 K temperatures. Also fluorescence measurements using pyrene as a photophysical probe have also been carried out for the present amino acid–surfactant systems.
