  • 摘要: 以Cu(CH3COO)2·H2O为铜源前驱物,水合肼为还原剂,通过浸渍的方法在棉布上负载纳米铜,成功制备了纳米铜膜。利用XRD和SEM对其进行了物相和形貌的表征,以亚甲基蓝(MO)、结晶紫(CV)、甲基橙(MO)和罗丹明B(RhB)等常见的8种染料为目标污染物,评价了其催化还原染料废水的性能。结果表明:制备的纳米铜膜表面的纳米铜颗粒近似球形,平均粒径约700~800 nm,能够加快还原反应中的电子转移,达到快速使染料废水快速脱色的目的。在25 ℃,纳米铜膜的大小为4 cm×6 cm,NaBH4的浓度为0.5 mol·L-1,所建立的纳米铜膜催化体系能在12 min内使20 μmol·L-1的RhB完全脱色,在相同体系下,同浓度的MB、CV和MO的脱色时间分别只需要10 s、30 s和10 min,膜材料重复使用16次以后的脱色效果仍然在98%以上,表现出良好的催化活性和循环性。
