METHOD FOR PREPARING MONODISPERSED IRON OXIDE NANOPARTICLES USING SUPER-HIGH PRESSURE HOMOGENIZER AND MONODISPERSED IRON OXIDE NANOPARTICLES PREPARED THEREBY
The present invention relates to a method for preparing monodispersed iron oxide nanoparticles using a super-high pressure homogenizer and monodispersed iron oxide nanoparticles prepared thereby. More specifically, the present invention relates to a method for preparing monodispersed iron oxide nanoparticles using a super-high pressure homogenizer, the method comprising the steps of: a) mixing an iron oxide precursor, distilled water, and a precipitant solution to prepare an iron hydroxide solution, and then passing the iron hydroxide solution through a super-high pressure homogenizer at a pressure of 500-2,000 bar at room temperature to obtain a precipitate; and b) washing the precipitate obtained in step a), followed by drying, and to monodispersed iron oxide nanoparticles prepared thereby.
