Synthesis of Magnetite Nanoparticles by Electrochemical Method using Pulsed-direct Current

Magnetite (Fe3O4) is one of the most important magnetic materials and is widely used in industry. In recent years, monodispersed magnetite nanoparticles have attracted increasing attention due to their good biocompatibility, strong superparamagnetic properties, low toxicity and easy preparation process [1]. Magnetite nanoparticles find many applications in the biomedical industry, such as targeted drug delivery, hyperthermia treatment, cell separation, magnetic resonance imaging, immunoassays and the separation of biochemical products [2]. They are also useful for environmental processes, such as the treatment of water and wastewater [3].
