摘要
利用Fe2 +/H2 O2 对 2 4 二氯苯氧乙酸 ( 2 4 D)进行催化氧化 ,通过GC MS和HPLC检测到反应过程的中间产物为 2 4 二氯苯酚、邻氯苯酚和对氯苯酚 ,氯离子则是从这些中间产物上释放 .通过离子色谱检测到小分子酸 ,如乙醇酸、乙醛酸、顺丁烯二酸 .提出了 2 4 D的Fe2 +/H2 O2 降解的可能历程 .
Catalytic oxidation of 24-dichlorophenoxyacetic acid (24-D) was investigated by Fe 2+ /H 2O 2 regent.24-dichlorophenol、2-chlorophenol,4-chlorophenol were identified as intermediates by GC-MS and HPLC.Chloride ion is released from these chloroderivatives in the medium.Short-chain acids,as glycolic,glyoxylic and maleic were detected by IC chromatography.The degradation pathway of oxidation of 24-D by Fe 2+ /H 2O 2 is proposed.
