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

Abstract

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