LIQUID-LIQUID EXTRACTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To increase an extraction efficiency by shortening treating time of liquid-liquid extraction and reducing variation of an extraction amount of a solute. SOLUTION: The liquid-liquid extraction system includes: a container storing a continuous phase and a dispersed phase being liquids incompatible with each other, and a solute dissolved at least in any one of the continuous phase and dispersed phase; a water tank containing the container and having water therearound; an emulsifying ultrasonic oscillation source disposed on a face outside the water tank and roughly parallel to an interface of the continuous phase and dispersed phase; a separation ultrasonic oscillation source disposed outside the water tank; an ultrasonic oscillation source drive circuit driving the emulsifying ultrasonic oscillation source and separation ultrasonic oscillation source; and a control part controlling the ultrasonic oscillation source drive circuit to drive the emulsifying ultrasonic oscillation source and separation ultrasonic oscillation source in this order.
