The thermodynamic properties of aqueous solutions of amino acids in presence of electrolytes have been extensively studied to understand their behaviour in aqueous solution and the role of solute–solvent interactions on the conformational stability of proteins. On the other hand, ionic liquids (ILs) are liquids are at or near room temperature in their pure state and have been widely used in a number of fields in both academia and industry. They exhibit many advantages such as low melting point (< 373 K), a wide liquid range, suitable viscosity, thermal stability, ability to dissolve a variety of materials and most important, negligible vapor pressure.Ionic liquids have been suggested as green and benign replacements for traditional volatile organic solvents and growing number of applications such as catalysis, chemical reactions, separations,electrochemistry, and nanoscience investigations [1].
