Magnetic CuO/CoFe2O4(CCF)composites are prepared via the hydrothermal method,and used to activate the peroxymonosulfate(PMS).CCF is characterized by means of SEM-EDS,XRD and XPS.With tetracycline as a target pollutant,the influence of the initial pH of solution,oxidant dosage,catalyst dosage and co-existing ions on the treatment of tetracycline by CCF activated PMS is explored.The results show that the removal rate of tetracycline can reach to 91%within 30 min when the temperature is 25℃,the initial concentration of tetracycline is 20 mg·L-1,...
