摘要：

Few studies using high frequencies have been carried out on the sono-TiO2 process, and consistent results based on the specific experimental conditions have not been reported thus far. Therefore, in the present work the effects of power density and dose on the kinetic constant of diethyl phthalate at 500 and 35 kHz using TiO2 have been evaluated. The slopes of kinetic constants depending on the power density regardless of TiO2 were increased and they were shown to be linear. However, the enhancement percentage according to the frequencies at 500 kHz was lower than that at 35 kHz, though clear discussions on the enhancement in the presence of TiO2 have not yet been produced. Also, the optimal dose was 1 g/L, which was not changed according to the frequency. (C) 2012 The Japan Society of Applied Physics
