Abstract
This work reports a simple process for preparation of stable and uniform magnetite nanoparticles (Fe3O4) at low temperature. The method is supported in three single steps and provides low-sized functionalized magnetite nanoparticles at lower temperatures than the obtained by similar methods. The samples have been characterized by x-ray diffraction (XRD), Fouriertransform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and vibrating sample magnetometry (VSM), where it shows the nature of the nanoparticles. This study reveals that these nanoparticles are spherical in shape and have an average size of 30 nm, they present a super-paramagnetic behavior, and IR spectra show the group of N-monosubstituted amides, CO-NH in the cover of the superparamagnetic nanoparticles which avoids their agglomeration..
