摘要
建立了一种快速有效地降解水体中杀虫剂灭多威的方法。采用微波诱导活性炭(MW/AC)催化技术对水体中灭多威的降解进行了研究。考察了微波照射时间、溶液初始浓度、催化剂用量和溶液酸度对灭多威降解的影响。对总体积25 mL、质量浓度50 mg/L的灭多威溶液,加入活性炭1.6g/L时,使用功率750 W、频率2 450 MHz的微波照射3.0 min,则灭多威降解率达84.11%。适当提高活性炭加入量至2.4 g/L,降解率即可达100%。MW/AC降解灭多威这一方法具有降解效率高、降解速度快、成本低、没有中间产物生成和无二次污染等优点,适合于灭多威废水的处理。
A kind of method of rapid and effective degradation of the insecticide methomyl in water was established.Microwave-induced degradation catalyzed by activated carbon technology（MW/AC） was used to degrade methomyl in the solution.The effects of MW irradiation time,methomyl initial concentration,catalyst dose and solution acidity on the degradation were assessed.The degradation ratio reached 84.11% for 25 mL solution with 50 mg/L methomyl under 1.6 g/L AC dose,3.0 min MW irradiation,750 W MW power and 2450 MHz frequency.The degradation ratio could reach 100% by appropriate increase of the AC dose up to 2.4 g/L.The degradation method of methomyl using MW/AC has some advantages including high degradation efficiency,rapid degradation rate,low cost,no intermediates and no secondary pollution.It showed that the method was suitable for treating HHmethomylHH waste water.
