Outline of Final Research Achievements |
The effect of ultrasonic irradiation on the decomposition of trace phenol in solution using nonthermal plasma which generates in aqueous solution was investigated. The 40-kHz ultrasound was indirectly irradiated to the plasma reactor. The streamer and spark discharges were employed as nonthermal plasma in aqueous solution. As a result, the discharge current of both of the streamer and spark discharges was increased by ultrasonic irradiation. In particular, its effect appeared clearly for spark discharge. However, the phenol decomposition was not improved by ultrasonic irradiation. In order to improve the phenol decomposition, it is necessary to examine the combination condition of plasma and ultrasonic irradiation.
