Abstract
Molecular interactions present between 1-pentadecyl-3-methylimidazolium bromide and the biologically important amino acid additives (glycine, l-alanine, and l-valine) have been examined in aqueous media by employing conductivity, UV–Visible, refractive index, and FT-IR spectroscopy at different compositions and temperatures. Furthermore, using the electrical conductivity data, critical micelle concentration, degree of counter-ion dissociation, and various thermodynamic parameters of micellization have been computed. To study the interactions in the micellar system, the effects of additives on these parameters have been carefully analyzed. UV–Visible and refractive index are carried out to outline the results stated above, along with FT-IR results to confirm the various interactions prevailing in the system.
