PREPARATION OF Fe/Mn-PAC CATALYSTS AND DEGRADATION OF REACTIVE BRILLIANT BLUE KN-R BY CATALYTIC OZONATION

  • 摘要: 为获得高效去除活性艳蓝的方法,采用浸渍煅烧法制备了Fe/Mn-PAC催化剂,对催化剂的表面形态和结构进行表征,研究了不同因素对KN-R降解效果的影响,以及催化剂的重复利用性和稳定性。结果表明:Fe/Mn-PAC催化剂表面粗糙,具有较多的微孔结构,催化剂表面的金属氧化物为致密的地衣状结构,有利于提升催化剂的催化性能。在催化剂投加量为400 mg/L,初始pH为7.5,Fe/Mn进料比为1∶1及负载量为4%时,Fe/Mn-PAC表现出最佳的催化KN-R降解的反应活性,45 min内KN-R去除率高达90%以上;经过5次回收利用,去除率仍可达到84.7%。研究结果证明了Fe/Mn-PAC催化剂具有优异的催化能力和出色的结构稳定性,为实现印染废水中活性艳蓝KN-R的有效去除提供了技术支持。
