| 摘 要： | 以累托石为载体,用液相合成法制备和表征了Cu2O/累托石纳米复合材料,并以吸附降解二甲酚橙的效果,探讨复合材料的吸附及光催化氧化性能.试验结果表明：当模拟二甲酚橙染料废水的初始质量浓度为20～30 mg/L,初始pH值为13,搅拌时间为40 min,纳米累托石/Cu2O复合材料的投加量为5 g/L时,对模拟二甲酚橙染料废水中二甲酚橙的去除率可达81.56%.三次重复使用后的复合材料对二甲酚橙的去除率仍可达70%.

| Abstract: | The Cu2O/rectorite composite which took the rectoite as the carrier was prepared by liquid phase synthesis and was characterized by means of SEM and XRD.The adsorption performances and photocatalysis properties of the composite was based on the photocatalytic degradation of simulate xylenol orange dye wastewater.The results indicate that the photodegradation efficiency of rectorite /Cu2O is 81.56% when stirring time is 40 min,initial pH of 13;simulate xylenol orange dye wastewater is 20—30 mg/L and the addtion of composite is 5 g/L.The photodegradation rate still reaches 70% even after repeated use for three times. |
