Application of ultrasonic irradiation and vortex agitation in solvent microextraction

•Application of ultrasonic irradiation in solvent microextraction.•Application of vortex agitation in solvent microextraction.•Tables show applications and the most important parameters in solvent microextraction.

Ultrasonic irradiation and vortex agitation were introduced to enhance the efficiency of solvent microextraction. The present overview covers ultrasound-assisted emulsification microextraction, ultrasound-assisted surfactant-enhanced microextraction, vortex-assisted liquid-liquid microextraction, vortex-assisted surfactant-enhanced emulsification liquid-liquid microextraction, ultrasound-assisted dispersive liquid-liquid microextraction and ionic liquid-based ultrasound-assisted dispersive liquid-liquid microextraction.
