Efficient Degradation of Ofloxacin by Magnetic CuFe₂O₄ Coupled PMS System: Optimization, Degradation Pathways and Toxicity Evaluation.

ABSTRACT: Magnetic CuFe₂O₄ was prepared with the modified sol-gel method and used for enhanced peroxymonosulfate (PMS) activation and ofloxacin (OFL) degradation. The OFL could almost degrade within 30 min at a catalyst dosage of 0.66 g/L, PMS concentration of 0.38 mM, and initial pH of 6.53 without adjustment, using response surface methodology (RSM) with Box-Behnken design (BBD). In the CuFe₂O₄/PMS system, the coexisting substances, including CO₃^2-, NO₃^-, SO₄^2-, Cl^- and humic acid, have little effect on the OFL degradation. The system also performs well in actual water, such as tap water and surface water (Mei Lake), indicating the excellent anti-interference ability of the syst
