灭多威的超声降解研究
Ultrasonic degradation of methomyl
  
中文摘要:
      研究了灭多威模拟废水在超声作用下的降解反应动力学、降解产物、降解途径、以及影响降解速率的因素等问题.结果表明,灭多威经超声作用35min,可被完全转换为无机物,其降解过程为假一级反应;浓度增加时,降解减慢; Fe2+和 H2O2对降解有促进作用,且 Fe2+促进作用比 H2O2的大;采用不同气体饱和溶液时,降解率的大小有下列顺序:Ar>O2>Air>N2.红外光谱表明降解产物为 SO24-、 NO3和 CO2.
英文摘要:
      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.
