Preparation of Polystyrene/Fe3O4 Suspension Filler and Fenton-like Treatment of Guaiacol Simulated Waste water
摘要
Abstract
Fenton-like reaction is one of the effective solutions to the problems of large dosage of chemical agents and large amount of iron mud production in homogeneous Fenton.In this study,polystyrene(PS)/Fe3O4 suspension filler was synthesized with Fe3O4-OH and styrene(St)as main raw materials by chain polymerization reaction,which was used for Fenton-like treatment of guaiacol simulated wastewater.Fourier transform infrared spectroscopy(FT-IR),thermogravimetry(TGA),ultra-depth of field microscope,scanning electron microscope(SEM)and X-ray energy spectrometry(EDS)were used to analyze and characterize the suspension fillers,and it was found that PS/Fe3O4 suspension fillers had a double-layer composite structure of Fe3O4-OH and polystyrene.The mass ratio of Fe3O4 is 51.6％.The degradation effect of PS/Fe3O4 suspension filler and nano Fe3O4 Fenton-like system on guaiacol was compared and studied.It was found that the treatment effect of PS/Fe3O4 suspension filler was better,and the optimal process conditions were as follows:The initial pH value was 4,m(CODCr)∶m(H2O2)=1∶1.5,the dosage of suspension filler was 0.8 g/L,the reaction time was 120 min,and the degradation rate of guaiacol reached 88.63％.The free radical quenching experiment showed that the main active free radical in the Fenton-like degradation system of guaiacol before and after Fe3O4 modification was·OH.关键词
