Synthesis of Iron Oxide Nanoparticles (Fe3O4)

A method of synthesis of Iron oxide Nanoparticles is explained. 50 mL of 0.2M Fe3+ salt solution (FeCl3) and 50 mL of 0.1M Fe2+ (FeSO4) was added to FeCl3 solution and stirred for 15 min. Then NH4OH was added dropwise until pH 11 and stirred further for 20 min.
