【摘要】 为克服Fenton氧化体系只能在酸性条件下使用且产生大量铁泥的缺陷,制备了8-羟基喹啉铁铜配合物(FeQ,FeCuQ)用于催化降解水中的苯酚。通过傅里叶变换红外光谱(FT IR)和紫外可见光谱(UV-Vis)对产物进行结构表征。采用静态实验,在室温(20℃)和初始pH为7条件下,考察了催化剂用量,H2O2浓度,反应时间,催化剂的稳定性等影响因素。对FeQ和FeCuQ进行了降解动力学初步分析。实验表明,FeQ和FeCuQ对苯酚氧化具有良好的催化活性。更多还原

【Abstract】 To overcome the drawback that Fenton oxidation system can only be used under acidic conditions and produce large amounts of iron mud,8-hydroxyquinoline iron and copper was prepared to catalyze degradation of phenol in water.The product was characterized by FT IR and UV-Vis.The influential factors of static oxidation reaction such as the amount of FeQ and FeCuQ,the hydrogen peroxide dosage,the reaction time and the catalyst stability at initial pH of 7 and room temperature were investigated.The kinetics of degradation of phenol was studied.The experimental results showed that FeQ and FeCuQ had good catalytic activty for oxidation of phenol.更多还原
