| Abstract: | The ultrasonic degradation of the waste water simulated by addition of methomyl to distilled water is described. The reaction dynamics, degradation products, degradation path and factors that effect the rate of degradation are studied. The results show that the methomyl has been converted into inorganic materials in 35 minutes of sonication and the degradation dynamics is first order reaction. On increasing the concentration of methomyl, the degradation rate decreases, Fe2 and H2O2 can both accelerate degradation, the action of Fe2 being stronger than that of H2O2. When the saturation gas in the solution is changed, the destruction rate follows the order:Ar>O2 >air>N2. IR study shows that the reaction products are SO24-, NO3- and CO2. |
