摘要：

The combination of ultrasound and photochemistry have been used to degrade an aqueous solution of 2,4,6-trichlorophenol. An ultrasonic probe of 22 kHz frequency and a UV tube of 15W have been used. Anatase grade TiO2 was used as the semiconductor catalyst. The effect of parameters such as ultrasonic intensity, operating conditions, type of ultrasonic equipment, and mode of UV transmission have been studied. The sonophotochemical degradation has been found to be dependent on the intensity of sonication, temperature of the reaction, and the type of ultrasonic equipment used, but was independent of the mode of UV transmission. Enhancement in the degradation rate has been observed at a higher sonication intensity and temperature of the solution. (C) 1998 Elsevier Science B.V. All rights reserved.
