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.
