Title: METHOD AND DEVICE FOR DESORBING SUBSTANCE ADHERENT TO PARTICULATE SUBSTANCE
Abstract:
A method for desorbing a desired substance from a particulate substance at higher efficiency. The method for desorbing a substance adherent to a particulate substance involves: a microbubble introduction step in which the particulate substance (2) from which an adherent substance is to be desorbed is held in a vessel (1) and immersed in a liquid, and microbubbles are introduced from a microbubble generator (61a) into the vessel (1); and an ultrasonic propagation step in which ultrasonic waves are propagated by means of ultrasonic vibrators (62a, 63a) to the inside of the vessel (1) containing the liquid filled with the microbubbles in the microbubble introduction step.
