Salting out effects on adsorption and micellization of three imidazolium-based ionic liquids at liquid-liquid interface

- Electrolytes fortify ILs interface activity at toluene-water interface.
- Sodium chloride has stronger effect on ILs adsorption than potassium chloride.
- The experimental data are well fitted with the Frumkin adsorption isotherm.
- Adsorption tendency and effectiveness increase with electrolyte concentration.
- Repulsive interaction of adsorbed molecules decreases with electrolyte concentration.
