    Abstract: 近年來研究指出Fenton對於毒性有機化學物質及染料廢水有很好的處理效果。但是廢水中若含有大量的陰離子可能對氧化反應產生影響。所以本研究將探討陰離子對Fenton程序去除苯胺的效應。本研究利用CO32-、PO43-、Cl-、NO3-、ClO4-五種不同陰離子和苯胺搭配,來模擬含有毒性物質之廢水,另外在加入亞鐵離子、雙氧水催化分解苯胺。實驗方式為採批式恆溫震盪,反應溫度30oC、震盪器轉速125rpm,並使用氣象層析儀來分析水中苯胺之殘留率,藉此評估各種陰離子的存在,對Fenton程序除苯胺的影響。 實驗結果顯示,Fenton對陰離子的存在很敏感,對採用的五種陰離子而言,H2PO4-存在時Fenton去除苯胺的效率最差,最主要抑制Fenton氧化能力的原因是H2PO4-會和亞鐵離子及鐵離子產生復合反應,降低亞鐵離子的催化能力,故無法有效去除苯胺。而Cl-、H2PO4-比ClO4-、CO32-、NO3-存在時,對去除苯胺影響較大。綜合本研究結果,五種陰離子抑制Fenton程序去除苯胺之能力大小為H2PO4->>Cl->NO3-~CO32-~ClO4-。
