Abstract: Provided is a method of easily manufacturing a solution-phase of zerovalent iron nanowires (INW), and more particularly, to a method of synthesizing zerovalent iron nanowires (INW) in which sodium boronhydride is added as a reducing agent to reduce ferrous sulfate mixed with poly(vinyl pyrrolidone). The present invention provides a simple and efficient method of synthesizing iron nanowires (INW) as one alternative to producing iron nanoparticles (INP). The INW manufactured by this method is very effective in removing groundwater contaminants such as arsenic, chrome (VI) and TCE. The highly reactive INW has great potential for producing an INW-based adsorbent for groundwater remediation.

Abstract: A method of synthesizing air-stable nano-scale zero-valent iron (NZVI) particles at room temperature is provided. Also, a method of treating environmental pollutants using nano-scale zero-valent iron synthesized by the above method is provided. According to the method, air-dried NZVI is very effective in removing pollutants such as arsenic, and the method is simple, cost-effective, environmentally friendly, and can stabilize the NZVI in air for more than 10 months.
