| 摘 要： | 乙腈是一种脂肪族的急性剧毒有机污染物,不仅危害大而且来源广泛,众多行业产生的污水中都包含乙腈。为了找到一种适合的DSA阳极来高效率地降解乙腈,对四种不同材料的阳极电极(钌铱钛(Ti/TiO2-IrO2-RuO2)、钌铱钛锡(Ti/TiO2-IrO2-RuO2-SnO2)、铱钽钛(Ti/TiO2-Ta2O5-IrO2)和铱钽钛锡(Ti/TiO2-Ta2O5-IrO2-SnO2))分别降解乙腈模拟废水的产物进行了研究,通过国标法测定不同时间段降解产物的COD值,比较四种阳极电极对乙腈模拟废水降解效果的优劣,结果显示在降解2.5小时时涂层含有铱钽钛元素的电极对乙腈的降解效果最佳。并以此电极为代表优化降解乙腈模拟废水条件,得到最佳条件为：PH为6.60,浓度为每500ml水中含1.32ml乙腈,电压为4.10伏,在此条件下降解率可达到69.0367%。

Degradation of acetonitrile wastewater by electrode containing iridium and tantalum elements |

| Abstract: | acetonitrile is a kind of aromatic organic pollutants. Not only harmful but also a wide range of sources.The drainage of many industries are contained acetonitrile. For the degradation of the high efficiency of acetonitrile wastewater, degradation of simulated wastewater with four kinds of anode((Ti/TiO2-IrO2-RuO2), (Ti/TiO2-IrO2-RuO2-SnO2), ( Ti/TiO2-Ta2O5-IrO2 )and (Ti/TiO2-Ta2O5-IrO2-SnO2)) and degradation effect was determined by national standard. The results showed that the degradation effect of Ti/TiO2-Ta2O5-IrO2 anode was good after 2.5 hours. On this electrode, the optimal conditions are found.The optimum reaction conditions with the degradation rate of 69.0367% were determined to be PH value of 6.60,acetonitrile dosage of 1.32ml,Voltage is 4.10v. |
