Abstract
Lecithin-adsorbed magnetic nanoparticles were prepared by three-step process that the thermal decomposition was combined with ultrasonication. Experimental parameters were three items-molar ratio between Fe(CO)5 and oleic acid, keeping time at decomposition temperature and lecithin concentration. As the molar ratio between Fe(CO)5 and oleic acid, and keeping time at decomposition temperature increased, the particle size increased. However, the change of lecithin concentration did not show the remarkable particle size variation.
