Catalytic Degradation of Ciprofloxacin in Aqueous Solution by Peroxymonosulfate Activated with a Magnetic CuFe₂O₄@Biochar Composite.

ABSTRACT: A magnetic copper ferrite and biochar composite (CuFe₂O₄@BC) catalyst was prepared by an improved sol-gel calcination method and initially used for the removal of antibiotics ciprofloxacin (CIP) by activated peroxymonosulfate (PMS). Using CuFe₂O₄@BC as the activator, 97.8% CIP removal efficiency could be achieved in 30 min. After a continuous degradation cycle, CuFe₂O₄@BC catalyst still exhibited great stability and repeatability and could also be quickly recovered by an external magnetic field. Meanwhile, the CuFe₂O₄@BC/PMS system presented good stability for metal ion leaching, which was far less than the leaching of metal ions in the CuFe₂O₄/PMS system. Moreover, the effects of
