ABSTRACT

We have developed a simple and easy Optimized-Reverse-Co-Precipitation Method (ORCPM) for the synthesis of Magnetite-Nanoparticles. This technique decreases the chances of agglomeration, broad particle size distribution and provides better nanoparticles as compared to simple co-precipitation method. The effect of different variables such as the temperature, N 2 -sparging, stirring rate, amount of capping agent and pH were studied and optimized for the synthesis of Magnetite-NPs by using the proposed method. Among these reactions each with varying parameters, we finally concluded that the best Optimized-Conditions for the synthesis of M-NPs were 0.2g Dextrin at 60℃ with 12 pH, stirring rate of 150 rpm and with the continuous nitrogen sparging, can give far better results than the existing co-precipitation technique. The synthesized M-NPs were characterized using Fourier Transform Infrared Spectroscopy, X-Ray Diffractometer, Scanning Electron Microscope and Zeta-Potential. It was found that synthesized Magnetite-NPs with current technique were of FCC-shape with an average particle size of 12.9nm.
