| 摘 要： | 采用等体积浸渍法制备FeZSM-5作为异相类Fenton氧化催化剂,使用XRD、FT-IR对FeZSM-5进行表征,探究反应温度、初始pH值、H_2O_2初始浓度、催化剂用量以及铁负载量对FeZSM-5催化H_2O_2氧化降解日落黄FCF脱色的影响,考察催化剂循环使用性能。结果表明,铁以Fe_2O_3形态存在于分子筛孔道内; FeZSM-5催化剂活性受反应温度影响较大,在最适宜条件下,铁负载质量分数为3.5%的FeZSM-5催化剂在FeZSM-5/H_2O_2类Fenton氧化反应体系中对日落黄FCF模拟废水脱色率达97.0%,且循环使用性能较好。

| Abstract: | FeZSM-5 was prepared by equal volume impregnation method for a catalyst in Fenton-like oxidation.XRD and FT-IR were used to characterize FeZSM-5.Effects of reaction temperature,initial pH,initial H2O2 concentration,catalyst dosage and iron loading amount on the oxidation of Sunset Yellow FCF in FeZSM-5/H2O2 systems were investigated.The reusability of FeZSM-5 catalyst was also examined.It was found that iron existed in pores of the molecular sieve in the form of Fe2O3.The catalytic activity of FeZSM-5 was greatly affected by temperature.In the optimal condition,decolorization of Sunset Yellow FCF in simulated wastewater reached 97.0% in FeZSM-5/H2O2 Fenton-like oxidation reaction system and FeZSM-5(iron loading mass fraction of 3.5%) exhibited a good recycling performance. |
