Abstract
Profoundly clarifying the corrosion characteristics of nanoscale zerovalent iron(nZVI)can provide a theoretical support for elucidating its based technology for environmental application. Herein,the electrochemical tests including the Tafel,electrochemical impedance spectroscopy(EIS) and open-circuit potential vs. time (OCPT) curves were employed to investigate the corrosion behaviors of sulfidated nZVI (S-nZVI) under different solution chemistries. It was found that the corrosion resistance and electrical conductivity of nZVI could be synergistically improved by the sulfidation with complex reagents. In addition,the fitting results of the OCPT further verifies that the initial corrosion rates of S-nZVI can be inhibited by the reagents,which implying that the reactivity of nZVI can be improved through tuning the mass transfer of the reactive species.
