SYNTHESIS AND CHARACTERIZATION OF IRON OXIDE (Fe3O4) PARTICLES BY CHEMICAL METHOD AND ITS APPLICATION
Abstract
- Iron oxide particles with appropriate surface chemistry exhibit many interesting properties that can be exploited in a variety of biomedical application such as magnetic resonance imaging contrast enhancement, tissue repair, hyperthermia, drug delivery and in cell separation. In this study, FeSO4.7H2O, NaNO3 and NaOH were used in the preparation of iron oxide by chemical method. The characteristic properties of iron oxide were studied by X-ray Diffraction (XRD), Fourier Transform Infrared (FT IR) spectroscopy and Scanning Electron Microscopy (SEM) and Thermogravimetric-Differential Thermal Analysis (TG-DTA). The crystalline nature of the prepared iron oxide was identified by XRD analysis. According to XRD data synthesized iron oxide (Fe3O4) by chemical method at 100 C was naturally stabilized cubic structure and in the average crystallite size of 39.27 nm. In FT IR spectrum of iron oxide the peaks at 895 cm-1 and 457cm-1 are due to the vibration of Fe-O group. The SEM micrographs of iron oxide prepared by chemical method at 100ºC indicated that the particles are spherical in shape with a narrow size distribution. TG-DTA analysis showed two endothermic peaks and one exothermic peak. Sorption properties of the prepared iron oxide was studied by model congo red dye. Since, the value of separation factor RL (from Langmuir isotherm) for this dye was 0.04, the adsorption was favourable adsorption.
