苯胺是一种典型的有毒污染物,在工业废水中较为常见,而常规处理技术对其处置效果不佳。光催化耦合臭氧高级氧化技术因为高效快速,具有广泛的应用前景,可以作为有毒有机污染物的处置手段之一。通过制备了一种C改性TiO2负载磁性活性炭(C-TiO2@Fe3O4/AC)催化剂,考察了其光催化耦合臭氧氧化处理苯胺的效果。研究结果表明,运行30min后即可达到95%以上的降解效率,苯胺去除率和反应效率均高于普通的C-TiO2和Fe3O4/AC催化剂。
Aniline is a typical toxic pollutant,which is common in industrial wastewater,but its treatment effect is poor by conventional treatment technology.Photocatalytic coupling ozone advanced oxidation technology has a wide application prospect because of its high efficiency and rapidity,and can be used as one of the disposal methods for toxic organic pollutants.AC-modified TiO2 supported magnetic activated carbon (C-TiO2@Fe3O4/AC) catalyst was prepared to investigate the effect of its photocatalytic coupled ozone oxidation on the treatment of aniline.The results showed that,after running for 30min,the degradation efficiency of aniline was more than 95%,and the removal rate and reaction efficiency of aniline were higher than those of ordinary C-TiO2 and Fe3O4/AC catalysts.
