摘要：Norfloxacin(NOR) is one of the most widely used antibiotics in animal farming and hospital.With the mass production and consumption, the large amounts of NOR was discharged into the water en-vironment which caused severe pollution problems. Advanced oxidation processes(AOPs)can decom-pose, mineralize most organic compounds, including NOR. In this paper, a novel AOPs catalyst based on peroxymonosulfate (PMS), Co3O4/Uio-66-NH, composites were prepared. The morphology and structure of the composites were shown in this paper. Degradation experimental results show that Co;O./Uio-66-NH, composites have better degrada-tion efficiency than Co;O4 nanoparticles, and the leaching concentration of cobalt ions is lower, indi-cating that the composite material has better stability than Co;O4 alone. Under the conditions of 1.0mM PMS and 0.2g/L Co;O4/Uio-66-NH2 dosage at neu-tral pH, about 90%of norfloxacin (NOR) can be de-graded within 30 min. In addition, the mechanism of PMS activation by Co;O4/Uio-66-NH2 composites were studied through the free radical identification by quenching experiments and electron paramag-netic resonance (EPR)technology. In addition, the Co;O4/ Uio-66-NH2 composites material has good regeneration efficiency, which has a certain applica-tion prospect for the removal of NOR from drinking water, and this work will also provide a potential contribution to the removal of NOR from the envi-ronment.
