Abstract : Magnetic nanomaterials are studied extensively because of their wide range of possible applications. Synthesis of Fe3O4 with citrate and polyethylene glycol (PEG) as stabilizing agents was carried out. In this study, the effect of media of water, sodium citrate and polyethylene glycol as stabilizing agents on the shape and size of Fe3O4 magnetite nanoparticles was investigated. The synthesis of Fe3O4, Fe3O4/citrate, and Fe3O4/PEG was carried out by the coprecipitation method at controlled pH. The products were characterized by infrared spectrophotometry, X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX). Qualitative test of magnetism was also carried out on the three materials. The results showed that Fe3O4 nanoparticles prepared with sodium citrate and PEG have a diameter of 12 and 10 nm, respectively. In the sodium citrate medium, it gives Fe3O4 colloidal nanoparticle with electrostatic stabilization mode, while in the PEG medium it shows steric stabilization mode. Magnetite produced in PEG medium has the homogeneous size and is much more stable than that obtained in citrate medium
