主　　题：Peroxymonosulfate(PMS)activation Heterojunction catalyst Electron migration Cu2O CoFe204 

摘      要：The electron transfer mechanism in the process of peroxymonosulfate(PMS)activation using heterojunction catalyst was *** this work,magnetic heterojunction Cu_(2)O/CoFe_(2)O_(4)(CC)was first synthesized to activate *** innovative reaction mechanism based on built-in electric field-driven electron migration from Cu2O to CoFe2O4 and effective magnetic moment of CC for enhancing PMS activation was ***,the CC/PMS system was used for efficient removal of antibiotic tetracycline(TC).Under optimal conditions,98.0%TC could be removed using CC/PMS catalytic system after only 30 *** catalytic activity was higher than that of Cu_(2)O/PMS and CoFe_(2)O_(4)/***,the impact of solution pH on TC removal was insignificant,suggesting the pH-insensitive PMS activation ability of ***,the coexisting inorganic ions in the environment,such as HCO_(3)-,H_(2)PO4-,NO_(3)-,Cl-and humic acid(HA)as representative of natural organic matter,did not inhibit TC removal in CC/PMS ***,CC/PMS system exhibited excellent reusability with more than94.0%TC removal after the 5th *** paramagnetic resonance(EPR)tests and quenching experiments showed that O_(2)·-and 1O_(2) played vital roles in TC *** intermediate products and corresponding toxicity assessment revealed that this catalytic system could reduce TC *** work provided new insights into the PMS activation mechanism using heterogeneous magnetic catalysts,including transition metal oxide.
