  • P-12 Sonochemical Effect under Free Surface using a Flow Ultrasonic Reactor

抄録

To optimize sonochemical reactors and design a more efficient reactor, it is important to know the sonochemical effects under free surface. As a measure of the sonochemical effects, we measured the production yield of I_3^- in aqueous solution of 0.1M KI under sonication. The ultrasonic frequency used here was 132.2 kHz and the experimental temperature was 25 ℃. The surface rise was observed above the transducer on sonication. The concentration of I_3^- under the free surface condition was larger than that obtained by using a reflector. This means that the sonochemical effect for free surface is enhanced. The results are interpreted in terms of the piston effect, which is induced by the fluctuation of surface and aeration. We will discuss the influence of the flow rate on the sonochemical effect under free surface condition for a continuous flow ultrasonic reactor.
