摘　　要：以草酸铁/过氧化氢为光氧化剂,利用自制的平板型光反应装置对有机磷农药乐果进行降解试验研究,结果表明有机磷农药乐果能被有效地降解。采用正交法设计试验方案,确定了最佳反应条件:初始PH值3、铁离子浓度40mg/L、双氧水浓度300mg/L、和辐射强度13.5w/m2。Dimethoates＇ decomposing reaction was studied using Ferrtoxatate/nyarogen as light oxidizing agents in a plate flat photocatalytic reactor under UV light. The results showed that Dimethoate can be degraded efficiently. The optimum reaction condition was determined by the orthogonal experiment method as the following： the initial pH=3, the Fe^3＋ concentration of 40mg/L, the hydrogen peroxide concentration of 300mg/L and the radiant intensity of 13.5w/m^2.
