Abstract

The continuous flow ultrasonic reactor with the maximum volume of 3.9l was designed and constructed and oxidation in aqueous solution of 0.1M KI using the continuous flow ultrasonic reactor was investigated at the frequency of 132.2kHz. It is found out that there is the limiting value of yield of I_3^- on the outlet of the reactor after longer sonication time. In this study, we estimated the rate constant of I_3^- in KI solution for the continuous flow ultrasonic reactor on the basis of the traditional modeling equation of the continuous flow reactor. The rate constant of I_3^- in the continuous flow ultrasonic reactor is larger than that in the batch one at a constant electric power. This means that sonochemical effect is enhanced for the continuous flow ultrasonic reactor. One reason is that the number of acoustic bubbles in solution may increase when the flow rate increases.
