| 摘 要： | 通过共沉淀法合成Ag3VO4,紫外光下以亚甲基蓝模拟染料废水为对象进行光催化降解实验,分析考察了催化剂的投加量、亚甲基蓝的初始浓度和通气量对光催化降解的影响。并用XRD,SEM,TEM和UV-vis漫反射对Ag3VO4的结构进行了表征。实验结果表明,紫外光下Ag3VO4降解亚甲基蓝有良好的催化活性,当催化剂用量为0.3g/L,通气量为2L/min以及初始浓度为10mg/L时,120min后亚甲基蓝的降解率达到98%。 |

| Abstract: | Ag3VO4 power was synthesized by precipitation method. Methylene blue was selected to simulate organic dye wastewater which was treated by photocatalytic oxidation using Ag3VO4 as photocatalyst under UV light irradiation. Effects of catalyst dosage,initial concentration of methylene blue and air flow rate on photocatalytic reactions were studied as well. Ag3VO4 powers were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM)and UV-vis diffuse reflect... |
