METHOD FOR PREPARING MONODISPERSED IRON OXIDE NANOPARTICLES USING ELECTRON BEAM IRRADIATION AND THE MONODISPERSED IRON OXIDE NANOPARTICLES, CAPABLE OF IMPROVING THE CRYSTALINITY OF THE NANOPARTICLES

摘要

PURPOSE: A method for preparing monodispersed iron oxide nanoparticles using electron beam irradiation and the monodispersed iron oxide nanoparticles are provided to simplify preparing processes by implementing the processes without surfactant and a dispersing agent.;CONSTITUTION: An iron oxide precursor is dissolved in distilled water in order to obtain a precursor aqueous solution(S100). A radical eliminating agent and a precipitating solution are added to obtain a hydrated iron(II) solution(S200). The hydrated iron(II) solution is stirred under room temperature and normal pressure. Precipitate is obtained by radiating electronic beam. A washing process and a drying process with respect to the precipitate are followed. The iron oxide precursor is FeCl_3, Fe_2(SO_4)_3, or Fe(NO_3)_3·6H_2O.;COPYRIGHT KIPO 2011
