Abstract

Iron-oxide nanoparticles were prepared by chemical coprecipitation method in inert gas atmosphere and also in air atmosphere in order to use them as possible nutrition source for plants. The samples were characterized by 57Fe Mössbauer spectroscopy, electron microscopy and PXRD measurements. The presence of considerable FeII contributions were indicated by 57Fe Mössbauer spectra. Furthermore TEM and XRD reflected nanomagnetite in washed and lyophilized samples prepared in inert gas atmosphere while the samples prepared in air atmosphere contained much higher amount of FeIII than characteristic of magnetite. In the case of samples prepared in inert gas, it was also shown that the immediate washing after the coprecipitation has a crucial influence on the FeII content of the nanomagnetites.
