Preparation of Iron Nanoparticles and Steel Plant Wastewater Treatment
The iron nanoparticles were prepared via a redox reaction between Fe2+ and BH4- in the SDS-ethanol-water system.The iron nanoparticles surface was treated by nickel salt solution. The particles were characterized by the Transmission Electronic Microscope(TEM) and X-Ray Diffraction(XRD).It is shown that γ type iron nanoparticles with a mean size of 50nm have been prepared. The wastewater in the steel plant was treated by the iron nanoparticles. It is shown that suspended substance and concentration of heavy metal ion in wastewater were brought down largely.
