Abstract The magnetic nanoscale cobalt ferrite (CoFe₂O₄) solid particles were prepared by the sol-gel method. These samples were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), fourier transform infrared spectrometer (FT-IR) and vibrating sample magnetometer. The activity of CoFe₂O₄ particles was evaluated with the removal experiments of tetracycline hydrochloride (TCH) in the activated persulfate oxidation system. The results showed that the particles calcined at 600℃ had the higher activity and lower metal ion leaching rate on the particle surface. The CoFe₂O₄ particles prepared at the optimized temperature had high activity in a wide pH range (4.4~9.0) in activated persulfate oxidation system. The TCH removal efficiency reached 82.0% after 4 hours of reaction with the experimental conditions of PDS₀ 1g/L, CoFe₂O₄ 1g/L, TCH₀ 50mg/L, 20℃, pH₀ 4.4. These particles still maintained high activity and structural stability after 10 cycles of reuse, and could be easily recycled due to its special magnetic properties.

Key words： heterogeneous activation sulfate radical magnetic nano-CoFe₂O₄ particles recycle tetracycline
