SYNTHESIS OF NANOPARTICLES Fe3O4/PEG/PPy-BASED ON NATURAL IRON SAND

Magnetic nanoparticles of Fe3O4/PEG/PPy have been synthesized from natural iron sand by co-precipitation and ultrasonic treatment method. The nanoparticles were synthesized using HCl as solvent and NH3 as co-precipitate. The nanoparticles synthesized at 700C in two different treatments. PPy composites were variated to obtain the magnetic properties of samples. The measurements that have been done for both samples were XRD (X-Ray diffraction) and SEM (Scanning Electron Microscopy). The XRD results showed that the samples were having a single phase in Fe3O4 and lattice parameter 8.393Å. Based on the results of SEM, the nanoparticles tends to form rough sperical in shape and distribution particles of Fe3O4/PEG/PPy A, B, C, and D sample were around 42-50 nm, 48-63 nm, 56-67nm and 49-67 nm.
