| Outline of Final Research Achievements |
The aim of the research is to develop an ultrasonic reactor with stronger and more stable steady ultrasonic wave locally in the reactor and to decompose difficlut-decomposed compounds without any other chemicals in water. The effects of the shape and the materials of the reactor and reflection plate on the sonochemical reaction were investigated by numerical analysis of sound pressure distribution in the reactor and experiment of KI oxidation. A standard difficult-decomposed compound TPPS was decomposed.
This work clarified the followings. 1) Ultrasonic wave sholud be released from the reactor bottom and be concentrated locally by a concave reflector with focal length of half of the liquid height which is set at the liquid surface. 2) Both the concave reflector and the reactor should have high sonic reflection ratio and hydrophobic surface. 3) It is best that both the concave reflector and the reactor are made of glass.
