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.
Claims14
A method of synthesizing zerovalent iron nanowires, comprising:
- a first step of preparing an aqueous FeCl3.6H2O solution containing a polymer by dissolving a polymer in water and adding FeCl3.6H2O;
- and
- a second step of reducing the aqueous FeCl3.6H2O solution by adding sodium boronhydride and stirring.
