摘要
用浸渍法制备了负载铁锰复合氧化物的活性炭,以分散染料的臭氧催化氧化为目标降解物研究其催化性能。负载铁锰复合氧化物催化剂的催化性能较单一负载铁、锰的活性高,催化剂的最佳焙烧温度为500℃,反应时间为10min,臭氧浓度为27.98mg/L;负载型活性炭与臭氧之间有协同作用,共同催化氧化分散染料。
This paper prepared catalyst of active carbon-loaded Fe-Mn composite oxides using method of impregnation and studied its properties that catalyzed ozonation of dispersedye waste water.The catalyst-loaded Fe-Mn composite oxides has higher activity than the catalyst only loaded Fe or Mn,the optimum maturing temperature is 500℃,reaction time is 10 min,ozone concentration is 27.98mg/L.There is a synergistic action between active carbon and ozone,catalyticly oxide dispersedye waste water.
