CoFe2O4@MoS2 was prepared by the hydrothermal method and used to activate permonosulfate（PMS）for the degradation of ciprofloxacin（CIP）in water. The successful preparation of CoFe2O4@MoS2 was confirmed by the characterization results obtained from SEM and XRD. Degradation results showed that the removal rate of CIP in the CoFe2O4@MoS2/PMS system can reached 74.38% in 120minutes, which is higher than the sum of the individual CoFe2O4@MoS2 and PMS systems, verifying the activation ability of CoFe2O4@MoS2 on PMS. The quenching experiment results indicated that the main oxidative active species in the system are ●OH、SO4●- and 1O2, with SO4●- and 1O2 playing a major role in the degradation of CIP. Based on density functional theory combined with HPLC analysis, eight possible products were obtained and two possible degradation pathways of CIP were proposed. The environmental risks of the degradation products were evaluated and predicted using the TEST program, and it was shown that, compared with the parent compound, most products exhibited reduced acute toxicity, weakened mutagenicity, decreased bioaccumulation and developmental toxicity, and significantly lower ecotoxicity. Additionally, the CIP removal rate of the CoFe2O4@MoS2/PMS system can still reached 60.04% after four cycles, and the XRD results demonstrated that the crystal structure of the catalyst did not undergo significant changes before and after the reaction, indicating the high efficiency and stability of the catalyst.
