Synthesis of Magnetic Iron-Oxide Nanofiber Composite using Electrospinning: An Absorbent for Removal of Nitrate from Aqueous Solution

This project is aimed at preparation of nano filters using recycled foam of food containers enriched by magnetic nanoparticles, for nitrate removal from water. The characterization of this electrospun magnetic nanofiber depicted a high capacity for nitrate adsorption. The Scanning Electron Microscopy (SEM), X-Ray powder Diffraction (XRD), Energy Dispersive Spectrometry (EDAX) and Inductively Coupled Plasma (ICP) had been applied for this survey. In addition, magnetic behavior of nanoparticles was evaluated by magnetization measurements. The functionality of designing filter against affecting parameters along with the relation of these parameters with each other on the removal efficiency of nitrate was evaluated. It is concluded from the results that the height of the nano filter and the amount of magnetic nanoparticles has the most significant effect on the nitrate removal from water among all other factors. Therefore, optimization techniques can assist to achieve highest efficiency.
