Catalytic Degradation of Tetracycline Hydrochloride by Coupled UV−Peroxydisulfate System: Efficiency, Stability and Mechanism

Magnetic CuFe2O4 powder obtained by sol−gel method and coupled photocatalysis was used to activate peroxydisulfate for tetracycline (TC) removal. A scanning electron microscope, X−ray diffraction Raman spectroscopy FT−TR were characterize the catalysts. The degradation efficiency stability of TC highest under neutral conditions. rate reached 91.1% within 90 min. removal total organic carbon reaches 39.6% optimal unique transfer property utilized achieve synergistic effect persulfate oxidation. main oxidizing substances involved in decomposition sulfate radicals hydroxyl radicals, over 84% could be maintained after five cycles experiments.
