Abstract: The ultrasonic effect on photocatalytic cleavage of H2S was reported in this paper. Ultrasonic radiation is enable to enhance the photocleavage of H2S in the alkali solution with suspension CdS as photocatalyst under 500 W Xe lamp irradiation. Here, the power of ultrasonic wave with the center frequncy 10.4 kHz is about 100 W. And the ultrasonic radiation area of ultrasonic transducer is 4.5 cm2. The mechanism of ultrasonic effect on photocleavage H2S has been discussed preliminarily.

Key words: H2S, photocleavage, ultrasonic effect
