The prepared MC is used to activate peroxydisulfate for eliminating multiple tetracycline antibiotics, such as oxytetracycline (OTC), tetracycline (TTC), and chlortetracycline (CTC) in simulated wastewater under UV-light irradiation. The photoactivated sulfate radical-advanced oxidation processes (SR-AOPs) towards the removal of tetracycline antibiotics matrix (initial concentration of 10.0~mg/L) using MC were initially investigated using a batch method. The results reveal that 97.5\% OTC, 95.2\% TTC, and 100.0\% CTC can be degraded in the MC/UV/PDS system in the presence of 2~g/L of MC and 1~mM of PDS. The degradation pathways of OTC, TTC, and CTC were clarified via liquid chromatography-mass spectrometry analysis and DFT calculations. The quantitative structure{\textendash}activity relationship analysis shows that the tetracycline antibiotics are transformed into their corresponding intermediates with lower toxicity within 8.0~min. A self-designed fixed bed reactor, in which the MC was packed into the annular channel, was adopted to test the long-term operation possibility of the MC in the continuous photoactivated SR-AOP system. The findings demonstrate that the whole antibiotics matrix can be removed completely within 22~h. This work is the first to demonstrate the use of MOFs as catalysts for SR-AOP to achieve continuous purification of simulated wastewater. The findings highlight a new possibility for the use of MOFs in large-scale wastewater treatment over.}, keywords = {DFT calculations, Metal-organic frameworks, Sulfate radical-advanced oxidation process, Tetracycline antibiotics, Wastewater treatment}, issn = {1385-8947}, doi = {http://doi.org/10.1016/j.cej.2021.133213}, url = {http://www.sciencedirect.com/science/article/pii/S1385894721047884}, author = {Jia-Sheng Wang and Xiao-Hong Yi and Xingtao Xu and Ji, Haodong and Amer M.
