Self-Organization of Cationic Surfactant in Hydrophilic Ionic Liquid in Aqueous Media at Various Concentrations

Abstract

Abstract The present work focus on the study of thermodynamical parameters of micellization of surfactant in the presence of altered concentrations of the ionic liquid. The conductivity measurement has been done to study the aggregation behavior of mixed system of SDS and ionic liquid [C3mim][Br] at various concentrations (0.04, 0.08 and 0.12 weight percent of IL) and temperatures break reserved for 5K from 298.15 K - 308.15 K. The measured data of conductivity have been employed to know the CMC. Thermodynamical parameters of aggregation such as standard Gibb’s free energy of micellization, standard enthalpy and entropy of micellization determined and discussed. Outcomes have been elucidated in terms of the impact of IL on the micellization process of the sodium dodecylsulphate.
