| 摘 要： | 以Al2O3为载体,分别采用超声辐射浸渍法和普通浸渍方法制备Fe-Ni-Mn/Al2O3催化剂。采用BET、XRD和SEM对催化剂的理化性质和孔结构进行了分析,以模拟酸性绿B废水为研究对象考察催化剂的催化性能。实验结果表明,浸渍溶液pH值和焙烧温度显著影响催化剂的性能。与普通浸渍法相比,超声浸渍法制备的Fe-Ni-Mn/Al2O3催化剂对酸性绿B脱色反应表现出较高的催化活性。

| Abstract: | In this study,with Al2O3 as the carrier,Fe-Ni-Mn/ Al2O3 catalyst was prepared with ultrasonic irradiation impregnation method and conventional impregnation method separately.The physicochemical properties and microstructure of the catalyst were examined by means of BET,XRD and SEM.With simulated wastewater containing Acid Green B,the catalytic performance of the prepared catalyst was examined.It was found that the pH value of impregnation solution and calcination temperature had significant effect on the properties of this catalyst.Compared with catalyst prepared with conventional impregnation method,Fe-Ni-Mn/Al2O3 catalyst prepared with ultrasonic irradiation impregnation method had higher catalytic activity in the decolorization process of Acid Green B. |
