| 摘 要： | 研究了草酸铁芬顿、ＵＶ／芬顿和暗芬顿工艺中草酸钾，Ｈ２Ｏ２，ＦeSO4浓度，pH值，反应时间和反应温度对降解对硝基酚的影响，得出引入Ｋ２Ｃ２Ｏ４并不能提高对硝基酸酚的降解率，但可以使降解反 在一较宽的pH范围内进行，且缩短了反应时间，ＶＵ／芬顿同暗芬顿对硝基酚具有相同的降解效果，三种工艺降解对硝基酚的最佳条件分别是，草酸铁芬顿：Ｋ２Ｃ２Ｏ４：Ｈ２Ｏ２：ＦeSO4=1:10:1（化学计量数（旧称摩尔比）]，pH=2-6,t=30min,UV/芬顿及暗芬顿，H2O2:FeSO4=10:0.1（化学计量数），pH=3-4,t=40min，反应温度对降解反应无影响。

3-ture on the degradation of p-Nitrophenol by using UV/Fe(C2O4)3/H2O2, UV/Fenton and Fenton and com-pares the degradation effect of p-Nitrophenol by these three systems, and concludes that adding K2C2O4 into the system couldn't improve the degradation of p-Nitrophenol, but it enables the reaction to take place in a wide pH range, and shortens the reaction time; UV/Fenton and Fenton have the same influence on the degradation of p-Nitrophenol but the optimum conditions for the degradation of
3-p-Nitrophenol by these three systems are UV/Fe(C2O4)3/H2O2:K2C2O4:H2O2:FeSO4=1:10:1、pH=2～6、t=30min, UV/Fenton and Fenton: H2O2:FeSO4=10:0.1、 pH=3～4、 t=30min, and the temprature has no influence on the degradation reaction. |
