Effect of Agitation Condition on Performance of Sonochemical Reaction

The agitation effects on sonochemical reaction were investigated using a sonochemical reactor at 486 kHz. Agitator type, rotation speed, and ultrasonic irradiation direction were changed and the sonochemical reaction performances of aqueous solutions of potassium iodide (KI) and tetraphenylporphine tetrasulfonic acid (TPPS) were measured. The installation of a turbine agitator led to increase in the sonochemical reaction rates of KI and TPPS for the irradiation from the bottom wall in the reactor. The sonochemical reaction rates of TPPS for the irradiations from the bottom and side walls increased with the rotation speed of the propeller agitator.
