| Abstract: | The influence of ultrasonic strength,pH,catalyst dosage on the photocatalystic degradation of methylene blue were evaluated.The methylene blue can be degraded easily in alkaline solution and the optimal condition is at pH 7.5,250 W of ultrasonic power and 0.2-0.4 g/L catalyst.The removal rate of methylene blue by the ultrasonic-photocatalystic is higher than that by ultrasonic or photocatalyst. |
