Abstract
A purification apparatus and a purification method using the purification apparatus. A solution stored in a solution storage tank is diffused/agitated with an ultrasonic wave. An air compressor transfers the solution to a reactor. The solution is mixed in the reactor with a solvent fed through another passage to produce a reactant.
