| Because of the textile printing and dyeing wastewater’s intense color,large discharge,complex composition,and difficult to biodegradation,it is harmful to environment if it is directly discharged into the environment without treatment.Therefore,the treatment of textile printing and dyeing wastewater is crucial.In this research,the self-made ferroferric oxide carbon-based(Fe3O4/CNFs)composites were used as a catalyst,and hydrogen was used as an oxidant to degradate textile printing and dyeing wastewater.The Fenton-like reagent can degradate the textile printing and dyeing wastewater without adjusting the pH value of the solution,and the catalyst can be easily separated and reused,which can effectively reduce the secondary pollution of the catalyst and the acid.The main research contents are as follows:(1)The electrospinning technology combined with the hydrothermal method was used to prepare the Fe3O4 carbon-based composite materials,and the effects of hydrothermal reaction temperature and time on the composites were investigated.The composites were characterized by X-Ray Diffraction(XRD),Scanning Electron Microscope(SEM),Transmission Electron Microscope(TEM),Raman and X-Ray Photoelectron Spectroscopy(XPS).(2)The Fe3O4 carbon-based composite materials were used as catalyst to degradate sodium dodecylbenzenesulfonate(SDBS),bromamine acid sodium(BAA),methyl orange(MO),investigated the effect of temperature,amount of catalyst and hydrogen peroxide on the degradation,and explore the possible degradation mechanisms.Through this research,it was found that the Fe3O4 carbon-based composites as a catalyst for Fenton-like technology has good degradation effects on SDBS,BAA,MO.In addition,within a certain range,the increase of degradation reaction temperature,the increase of the amount of catalyst and hydrogen peroxide can promote degradation. |
