| 英文摘要 | In present work, an efficient purification of selenite-contaminated water using electrolysis-assisted nano zerovalent iron (E-nZVI), which achieved a removal capacity of 15.83 mg Se(IV)/g nZVI and exceeded the none assisted nZVI system by 135% was tested. Although Se(IV) removal dramatically increased with applied voltages over 2.0 V in E-nZVI system, the kinetics indicate that higher applied voltage (-4.0 V or more) and lower resistance could not result in apparent promotion on the reaction rate constant. Furthermore, the results from separate anode-cathode tests and surface-sensitive quantitative characterization reveal the synergistic effects of nZVI and cathodic reduction on elemental selenium precipitation, and nZVI corrosion aggravated by electrochemical oxidization improved removal performance in the anode chamber. In conclusion, the electrolysis assisted nZVI showed good removal efficiency of Se(IV) and is a potential water treatment method for removing reducible contaminants. |
