Abstract
This paper delineates the effect of hydrophilic ionic liquid 1âbutylâ3âmethylimidazolium chloride on micellar behavior of cationic surfactant cetyltrimethylammonium bromide (CTAB). Significant physicochemicalproperties like conductance, critical micelle concentration are detected to change as [C4mim][Cl] is added to aqueous CTAB. The conductivity data of surfactant CTAB in aqueous solutions of ionic liquid were experimentally determined in the temperature range from 298.15 to 308.15â¯K with the interval of 5â¯K. Obtained experimental data of conductivity have been utilized to deduce the critical micelle concentration (CMC). Using temperature dependence of CMC secured from conductivity measurements numerous thermodynamic parameters of micellization namely standard enthalpy of micellization (ÎHm0), standard free energy of micellization (ÎGm0), and standard entropy of micellization (ÎSm0) have been evaluated. FT-IR Spectra recorded for individual IL and some selected concentration to analyze the structural changes prevailed in the system. Results have been discussed in terms of effect of hydrophilic ionic liquid 1âbutylâ3âmethylimidazolium chloride [C4mim][Cl] on the micellization process of the surfactant cetyltrimethylammonium bromide (CTAB).
