Investigation on dispersion media in characterization of magnetite nanoparticles

In nanotechnology characterization of nano products is a very important step. There are some general characterization methods which were commonly used by nano researchers. Scanning electron microscopy is one of these methods. In this research The magnetite nanoparticles were synthesized by coprecipitation of aqueous Fe+3 and Fe+2 ions in presence of sodium hydroxide as the alkaline agent. The synthesized nanoparticles were dispersed in the three dispersion media including water, ethanol and ethyl acetate. Scanning electron microscopy is performed to characterize the nanoparticles.
