In this work,b.ron(b.was used to promote Fe^(3+)/peracetic acid(Fe^(3+)/PAA)for the degradation of sulfamethazine(SMT).An SMT degradation efficiency of 9.1%was ob.erved in the Fe^(3+)/PAA system over 60 min,which was significantly increased to 99.3%in the b.Fe^(3+)/PAA system over 10 *** b.Fe^(3+)/PAA process also exhib.ted superior resistance to natural sub.tances,excellent adaptab.lity to different harmful sub.tances,and good removal of antib.otics in natural fresh water *** mechanism of action of b.ron for Fe^(3+)reduction was determined using scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),Fourier transform infrared(FT-IR)spectroscopy,density functional theory(DFT)calculations,and electrochemical *** dominant role of^(·)OH was confirmed using quenching experiments,electron spin resonance(EPR)spectroscopy,and quantitative *** radicals(R-O^(·))and Fe(IV)also significantly contrib.te to the removal of *** calculations on the reaction b.tween Fe^(2+)and the PAA were conducted to further determine the contrib.tion from ^(·)OH,R-O^(·),and Fe(IV)from the perspective of thermodynamics and the reaction *** b.ron dosages,Fe^(3+)dosages,and initial pH values were also investigated in the b.Fe^(3+)/PAA system to study their effect of SMT removal and the production of the reactive ***(IV)production determined the k_(R-O·+Fe(IV))value suggesting that Fe(IV)may play a more important role than R-O^(·).A comparison of the results with other processes has also proved that the procedure describ.d in this study(b.Fe^(3+)/PAA)is an effective method for the degradation of antib.otics.
