Abstract :
The aim of this study is to obtain polysaccharide (Glucose, Fructose and Sucrose) stabilized superparamagnetic iron oxide nanoparticles (SPIONs) by Co-Precipitation method. As prepared iron oxide nanoparticles have been characterized by X-ray Diffraction (XRD), Fourier Transform infrared (FTIR) spectroscopy, UV–Vis NIR spectroscopy, High Resolution Transmission Electron Microscope (HRTEM) and Vibrating Sample Magnetometer (VSM). The average crystallite sizes as determined from XRD for Glucose–Fe3O4 (GF), Fructose–Fe3O4 (FF) and Sucrose–Fe3O4 (SF) are 3.3, 4.82 and 5.23 nm, respectively. Powder XRD study also demonstrates that the synthesized nanoparticles are indexed for spinel cubic lattice. FTIR spectrum shows a good vibrational interaction between Fe3O4 and polysaccharides functional groups and it controls the growth of Fe3O4 nanoparticles. SPIONs exhibit superparamagnetic properties with a coercivity ranging from 0.55 to 9.13 Oe and a saturation magnetization in the range 38-42 emu/g.
