Extraction in which ultrasound energy is used to increase the extraction rate by enhancing the contact area between the sample and solvent and by promoting efficient agitation.
Notes:
- Ultrasound energy is applied to samples in a vessel immersed in a water bath or applied more directly using devices, such as horns, probes, or sono-reactors.
- Ultrasound energy causes cavitation in solvents, which generates numerous tiny bubbles in liquids and mechanical erosion of solids, including particle rupture. It promotes digestion and slurry formation with solids and homogenization and emulsification with liquids.
