Abstract
The present invention describes a method and apparatus for aqueous extraction of chemical compounds from solid material in which the solid material is entrained in an extraction liquid phase that flowed around immersed sonotrodes emitting radial or focused high energy ultrasonic waves. A significant increase in extracted material and decreases in extraction time is observed.
