该文利用 Fenton法降解水中农药中间体3，4二氯三氟甲苯（3，4 DCBTE）。为评估 Fenton法处理3，4 DCBTE 时的降解特性，对初始 pH，H2 O2／ Fe2＋投加比率和温度 Fenton等不同反应参数及 Fenton 法氧化3，4 DCBTE的降解产物进行了研究。结果表明在 H2 O2投加量为2．67 g／ L、温度为20℃、H2 O2／ Fe2＋配比为15、pH为3的最优条件下反应2 h，3，4 DCBTE去除率高达93．1％。结合数据进一步分析，推测3，4 DCBTE最终被氧化生成氯苯。

The degradation of herbicide pesticide intermediate,namely 3,4-dichlorobenzotrifluoride (3,4 DCBTE)by Fenton reaction in aqueous solution was studied in this paper. In order to estimate the degradation characteristics of 3,4 DCBTE,several operating parameters,such as initial pH,ratio of H 2 O2 / Fe2 + and temperature,were investigated. Degradation products of 3,4 DCBTE by Fenton reaction were also studied. The results show that removal rate of 3,4 DCBTE by Fenton oxidation can reach to 93. 1% under the optimal condition as follows:H 2 O2 is 2. 67 g/ L,ratio of H 2 O2 / Fe2 + is 15,pH is 3,temperature is 20 ℃ and reaction time is 2 h. Further data analysis indicates that the 3,4 DCBTE is eventually degraded into chlorobenzene.
