Synthesis of Monodisperse Magnetite: The Effect of Temperature, Sodium Hydroxide and Citric Acid Concentrations on the Size of Nanoparticles


The effect of temperature, sodium hydroxide and citric acid concentrations on the size of magnetic magnetite nanoparticles was studied. Optimal conditions for synthesis of magnetite stabilized by citric acid with narrow size distribution were found. The average size of the nanoparticles determined by dynamic light scattering and transmission electron microscopy 12 ± 3 and 6 ± 2 nm, respectively was established. The chemical composition and structure of magnetite nanoparticles was confirmed by X-ray diffraction method.
