Abstract

This study aimed to obtain a particle size-based nano Fe₃O₄ iron sand, determine the effect of Polyethylene Glycol (PEG) -6000 with a ratio of 1: 3.1: 4,1,5 and without PEG against Fe₃O₄.Nanopartikel Fe₃O₄ nano particle size produced from iron sand which in synthetic by using coprecipitation method. 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) to determine the crystal size and content of the phase.

From the test results of X-Ray Diffractometer (XRD) to Fe3O4 without template PEG-6000 showed 29.08 nm crystal size, while Fe₃O₄ with the addition of PEG-6000 with a ratio of 1: 3; 1: 4; 1: 5 is: 14.90 nm; 22:16 nm; 33.11nm, the volume fraction of magnetite (Fe₃O₄) without PEG = 38.47%, with PEG 1: 3 = 48.39%; 1: 4 44.41%; 1: 5 = 53.20%

Keywords: Nanoparticles Fe3O4, Polyethylene Glycol (PEG) -6000, Coprecipitation.
