| 中文摘要 | Tetracycline is widely used in human and animal treatment of infectious disease. Because it is biologically active, stable and non-biodegradable, release to the environment threatens aquatic life and increases the risk posed by antibiotic-resistant pathogens. Therefore, treatment of this antibiotic in waste effluents is important. The degradation of tetracycline by photo-electro-Fenton oxidation was investigated in an electrolysis cell with a fabricated Fe3O4-graphite cathode. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronocoulometry were used to characterize the composite electrode. Comparisons of tetracycline degradation by electro-Fenton, UV irradiation and photo-electro-Fenton processes were investigated. Degradation efficiency was in order: photo-electro-Fenton > electro-Fenton > UV irradiation. The effects of applied current density, pH and UV irradiation on tetracycline degradation were investigated. High performance liquid chromatography (HPLC), UV-Vis absorption spectra, Fourier transform infrared spectroscopy (FT-IR) and total organic carbon (TOC) were used to investigate the decomposition of tetracycline and results showed that complete mineralization was possible. The Fe3O4-graphite cathode was stable and could be reused without catalytic decrease, suggesting its potential application in the tetracycline wastewater treatment.
