Abstract
The invention aims to reduce the processing time of liquid-liquid extraction, reduce variations in the amount of extraction of a solute, and improve the extraction efficiency. Provided are a container adapted to contain a continuous phase and a dispersion phase that are mutually immiscible liquids, and a solute dissolved in at least one of the continuous and dispersion phases, a water tank accommodating therein the container and containing water around the container, an emulsification ultrasonic oscillation source disposed outside the water tank, on a plane substantially parallel with the interface between the continuous and dispersion phases, a separation ultrasonic oscillation source disposed outside the water tank, an ultrasonic-oscillation-source driving circuit configured to drive the emulsification ultrasonic oscillation source and the separation ultrasonic oscillation source, and a control unit configured to control the ultrasonic-oscillation-source driving circuit such that it sequentially drives the emulsification ultrasonic oscillation source and the separation ultrasonic oscillation source.
