摘要

摘要:以AlCl3·6H2O、FeO3-6H2O和CO(NH2)2为原料,采用均相沉淀法制备了Fe2O3/Al2O3催化剂,并用x射线衍射(XRD)对其进行了表征。在Fe2O3/Al2O3存在下,采用微波诱导氧化法(MIOP)处理合成甲基橙废水。对影响甲基橙脱色的因素进行了研究,结果表明:在一定条件下(催化剂用量2g/L,微波功率900W,辐照时间5min,不调节pH),甲基橙(含20mg/L)的脱色效率接近93.2%。动力学结果表明,处理过程符合一级反应,为染料废水脱色提供了一种有效的技术。

Notice of RetractionTreatment of Methyl Orange Wastewater by Microwave-Induced Fe2O3/Al2O3 Catalytic
Abstract-The catalyst of Fe2O3/Al2O3 was prepared by homogeneous precipitation method using AlCl3·6H2O, FeO3-6H2O and CO(NH2)2 as material, characterized by X-ray diffraction (XRD). In the presence of Fe2O3/Al2O3, the microwave induced oxidation process (MIOP) was conducted for the treatment of synthetic methyl orange wastewater. The factors influencing color removal of methyl orange were investigated and the results showed that: under a given condition (catalyst dosage 2g/L, microwave power 900W, irradiation time 5 min, without adjusted to pH), the color removal efficiency of methyl orange (containing 20mg/L) approached 93.2%. The kinetics results show that the process of treatment accords to first order reaction .It provides an effective technology for the color removal of dye wastewater.
