摘　　要：以有机化合物氯酚（ＣＯＤ）为模拟废水，在铁离子催化剂参与下，用Ｈ２Ｏ２催化氧化氯酚。实验结果表明：在铁离子（Ｆｅ２＋或Ｆｅ３＋）催化下，Ｈ２Ｏ２可以迅速分解产生羟基自由基，羟基自由基能在很短的时间内将氯酚迅速氧化分解，反应１０ｍｉｎ后已测不出反应液中所含氯酚。最终ＣＯＤ的去除率在８０％以上。Ｈ２Ｏ２浓度、催化剂浓度、溶液的ｐＨ值等因素对ＣＯＤ的去除率均有影响。In this paper, chlorophenol was selected as model compound subjected to oxidation using hydrogen peroxide with iron ion(Fe 2+ or Fe 3+ ) as catalyst. Test results indicated that hydrogen peroxide was decomposed into hydroxyl radical with iron ions as catalyst. Dissolved chlorophenol can be effectively oxidized and completely removed from aqueous solution in a period less than ten minutes. An average COD lowering of over 80% was obtained. The amounts of H 2O 2、Fe 2+ or Fe 3+ and pH are three leading factors affecting the removal of chlorophenol.
