Abstract In this paper, the effect of zero-valent iron (Fe0) activated persulfate (PDS) on removal enrofloxacin (ENR) was investigated, and mechanism were analyzed by exploring effects Fe0 concentration, PDS pH, influence anion aqueous matrix ENR Fe0/PDS system. The results showed that when [ENR] = 20 µmol/L, [Fe0] 0.15 g/L, [PDS] 0.4 mmol/L, rate 85.3% at 90 min, mainradicals HO•, SO4•− O2•−. At same time, system had a good mineralization (TOC > 40%), in addition, did not show obvious toxicity to soil microorganisms after reaction, furthermore wide pH range (4 ≤ 10). more effective than ultrapure water removing river water. experiment could provide reference for antibiotics based advanced oxidation techniques SO4•−.

In recent years, pollution stemming from pharmaceuticals has garnered widespread global concern, which exacerbates the ecological risk to both surface and groundwater. current study, Fe O co-embedded biochar (Fe-O-BC) was synthesized through a one-step pyrolysis procedure with corncob serving as feedstock. The fabricated Fe-O-BC catalysts were characterized by various techniques employed for activation of peroxymonosulfate (PMS) degrade tetracycline (TC). TC rapidly degraded within 40 min, degradation rate 0.1225 min−1, much higher than those O-BC/PMS (0.0228 min−1) Fe-BC/PMS (0.0271 under same conditions. effects PMS dosage, dose, initial pH value coexisting anions investigated. Finally, mechanism oxidation in catalytic system implored experiments determining active sites radical scavenging experiments. C-O-Fe bond catalyst confirmed be dominant accelerating degradation. Free diffused HO•, surface-bound HO• SO4•− O2•−participated reaction absorbed SO4•−, predominantly contributed This study provides an efficient green alternative pharmaceutical wastewater treatment co-doped catalyst-induced heterogeneous process.
