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
