FTIR spectrum of the iron oxide nanoparticle (magnetite) spheres prepared by the hydrothermal method. This analysis was carried out in a JASCO 6200 FTIR (Japan) spectrometer with SPECTRA MANAGER V2 software. The sample was prepared by grinding 1–1.5 mg of dry particles with 150 mg of potassium bromide powder and pressing the mixture with a pellet-forming die. Analysis was done with 50 scans, at a resolution of 4 cm−1.
