Oxidative Degradation of Tetracycline by Magnetite and Persulfate: Performance, Water Matrix Effect, and Reaction Mechanism.

ABSTRACT: This study presents a strategy to remove tetracycline by using magnetite-activated persulfate. Magnetite (Fe₃O₄) was synthesized at high purity levels-as established via X-ray diffractometry, transmission electron microscopy, and N₂ sorption analyses-and tetracycline was degraded within 60 min in the presence of both magnetite and persulfate (K₂S₂O₈), while the use of either substance yielded limited degradation efficiency. The effects of magnetite and persulfate dosage, the initial concentration of tetracycline, and the initial pH on the oxidative degradation of tetracycline were interrogated. The results demonstrate that the efficiency of tetracycline removal increased in line with magnetite and persulfate dosage. However,
