In this study, the experimental conductivity, fluorescence, and UV spectroscopy study have been done for aqueous solutions of sodium dodecyl sulfate (SDS) and in aqueous ionic liquid (IL) 1-butyl-3-methylimidazolium chloride [C4mim][Cl] solutions at a temperature of 298.15 K. Experimental conductivity measurement has been done at different temperatures from 298.15 to 308.15 K. Moreover, the critical micelle concentrations (CMCs) of the mentioned systems were determined by different methods; furthermore, the CMC values have been utilized to originate the values of thermodynamical parameters of micellization like standard enthalpy of micellization (
), the standard free energy of micellization (
), and standard entropy of micellization (
). Fourier transform-infrared (FT-IR) spectra have been recorded to investigate the interactions and structural changes that occurred in the mixed system. Work has been discussed in terms of the effect of the aqueous IL solution on the micellization process of the SDS.
