Abstract

This study aimed to obtain a particle size-based nano Fe30 4 iron sand, determine the effect of Polyethylene Glycol (PEG) -6000 to be produced from iron sand in synthetic by using coprecipitation method and the nature of magnetization. Synthetic done by mixing natural sand with HCl as solvent and NH4OH as a precipitant, as templates are added PEG-6000 .. Then, characterized by using X-Ray Diffractometer (XRD). Vibrating Sample Magnetometer (VSM) and Fourier Transform Infra Red (FTIR). From the test results (XRD) shows the crystal size Preparation Fe3O4 nanoparticles with PEG 6000 (1: 3), (1: 4), (1: 5) in a sequence that is 14.90 nm, 22:16 nm, 33.11 nm while without PEG 6000 29.08 nm, Vibrating Sample Magnetometer measurement results (VSM) shows that the value of Ms saturation field for without PEG-6000 Fe3O4, Fe3O4 with PEG-6000 (1: 3), (1: 4), (1: 5) respectively 27.9 emu/g, 47.4 emu/g, 35.3 emu/g, 51.7 emu/g and field coercivity (Hc), each for 0,013 Tesla, 0.022 Tesla, Tesla 0.14, 0.009 Tesla. FTIR results showed that there was a shift peaks indicating increased number of PEG. From each sample came the peak of Fe-O owned by Fe30 4 where the wavelength of Fe-O at sample PEG has a lower value than the wavelength Fe3O4 caused the PEG.
