| Summary: | This research aims to treat the refractory nitrobenzene wastewater in the industrial water treatment industry with modified supported TiO2, and to study its influence on the treatment effect.Experiments have found that by preparing Fe and N co-doped TiO2/GF supported catalysts, it has better catalytic performance. Under the same conditions, Fe and N co-doped TiO2/GF can degrade nitrobenzene wastewater better than single Doped with Fe-TiO2/GF and N-TiO2/GF, the removal rates of nitrobenzene and COD are as high as 97.2% and 92.5%, respectively.The Fe and N co-doped TiO2/GF catalyst overcomes the agglomeration of traditional powdered TiO2 in solution, and has a good removal effect on nitrobenzene wastewater.
