Abstract:
The goal of this research was to use ferrous chloride tetrahydrate and ferric chloride hexahydrate (Fe2+ / Fe3+ = 0.5) as precursors in a co-precipitation method at room temperature, in a controlled atmosphere [1-2].Physical, structural and morphological characterizations of magnetite nanoparticles were performed. The obtained materials were characterized by a suite of physico-chemical techniques such as: X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDAX); the determination of surface area, pore volume and pore size was achieved by Brunauer–Emmett-Teller (BET) method.This primary study delivered sufficient data to focus supplementary investigations on factors that might have an effect on the efficiency of magnetic iron oxide. The investigation methods used in this study for the complex characterization of the materials and the results presented might lead to a better understanding of the adsorption phenomena and might help to develop new materials based on magnetic iron oxide nanoparticles for various applications such as remediation of marine environment, site remediation and groundwater treatment.
