Electrolyte effect on adsorption and the phase transition from microstructures to nanostructures in ionic/ionic surfactants mixture

► Energies are calculated by utilizing the new model of our previous work in various concentrations of salt. ► The obtained results show that transfer free energy decreased with increase of salt concentration. ► The variations of electrostatic, transfer and steric free energies were determined by using cyclic voltammetry data. ► The phase transition between mixed micelle and vesicle in presence of electrolyte was investigated by modified capacitor model.
