A kind of typical organophosphate insecticide, methylparathion pesticide, was degradated by nano anatase catalyst under a variety of affecting factors. The results indicated that the effects of ultras onic degradation was more obvious in the presence of nanoanatase. The ultrasonic degradation kinetics of methylparathion pesticide in the presence of nano anatase catalyst followed the first-order reaction. The degradation ratio of methylparathion pesticide surpassed 94.2 % within 40 min under ultrasonic frequency of 50kHz, amount of 2000mg.L-1 catalyst, output power of 40W, pH of 6.00, and temperature of 30°C, methyl parathion pesticide concentration of 40mg.L-1. |
