摘 要: | 对硝基苯酚是一种芳香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对硝基苯酚。为了找到一种适合的DSA阳极来高效率地降解对硝基苯酚,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))分别降解对硝基苯酚模拟废水的产物进行了研究,通过紫外分光光度法测定不同时间段的降解产物在最大吸收波长处的吸光度,比较四种阳极电极对对硝基苯酚模拟废水降解效果的优劣,结果显示涂层含有铱钌钛元素的电极对对硝基苯酚的降解效果最佳。由此讨论电极涂层材料在降解过程中所起的作用,提出电极的降解机理。

Abstract: | P-nitrophenol is a kind of aromatic organic pollutants. Not only harmful but also a wide range of sources.The drainage of many industries are contained p-nitrophenol. For the degradation of the high efficiency of P-nitrophenol 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 UV spectrophotometry. The results showed that the degradation effect of Ti/TiO2-IrO2-RuO2 anode was good. The effect of electrode coating material is discussed and Proposed degradation mechanism. |
