Abstract
Fe3O4 nanoparticles based on natural iron sand from Buaya river in DeliSerdang had been synthesized by co-precipitation and ultrasonic method. The HCl and NH3were used as solvent and precipitation agent, respectively. The Fe3O4/PPy nanocomposite wassynthesized at a low temperature of 70°C with 10gPpy. The structural and morphology of the Fe3O4/Ppy were characterized by X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FT-IR), and Thermo Gravimetric Analysis (TGA). XRD analysis confirmed that the crystal structure of the sample was cubic spinel with lattice parameter a = 8.3656 Å and the highest dhkl field at the millier index (311).This indicatedthe reduction in agglomeration of the sample.The results of FTIR analysis showed that PPy was successfully well correlated with Fe3O4 nanocomposites. TGA analysis showed a mass reduction of about 20% at 800°C this is due to the interaction between Fe3O4/PPy and the addition of polymer PEG 6000.
