In this paper, the effect of zero-valent iron (Fe 0 ) activated persulfate (PDS) on the removal of enrofloxacin (ENR) was investigated, and the effect and mechanism were analyzed by exploring the effects of Fe 0 concentration, PDS concentration, pH, and the influence of anion and aqueous matrix on the removal of ENR by the Fe 0 /PDS system. The results showed that when [ENR] = 20 µmol/L, [Fe 0 ] = 0.15 g/L, [PDS] = 0.4 mmol/L, the removal rate of ENR was 85.3% at 90 min, the mainradicals were HO • , SO 4 •− and O 2 •− . At the same time, the system had a good mineralization effect (TOC removal rate > 40%), in addition, the system did not show obvious toxicity to soil microorganisms after the reaction, furthermore the Fe 0 /PDS system had a good removal effect on ENR in a wide pH range (4 ≤ pH ≤ 10). There is basically no difference in the removal rate of Fe 0 /PDS system in ultrapure water and river water. The results of this experiment could provide a reference for the removal of antibiotics based on advanced oxidation techniques based on SO 4 •− . Supplementary Information The online version contains supplementary material available at 10.1038/s41598-024-78510-3.

The Fe0/PDS system was more effective than ultrapure water in removing ENR in river water. The results of this experiment could provide a reference for the removal of antibiotics based on advanced oxidation techniques based on SO4•−.
