The polymer coated Magnesium Ferrite nanoparticles (MgFe 2 O 4 ) based on natural iron sand, Mg(CH 3 COO) 2 .4H 2 O, and PEG-6000 have been successfully prepared by co-precipitation method. The mass variation of PEG-6000 content was from 0 to 12 gram. It was prepared at synthesize temperature of 70 o C. The PEG coating reduced the effect of agglomeration, so the coercivity value can be closed to soft magnets. The nanoparticle of synthesized has MgFe 2 O 4 single phase and cubic spinel structure. The bonding of MgFe 2 O 4 and PEG-6000 as a coating material was confirmed by FTIR curve. The MgFe 2 O 4 density decreased with the increasing of PEG 6000 content. On the other hand, the coercivity value was slightly reduced as the addition of PEG-6000, with the lowest value was obtained on 8 gram PEG content. The optimum condition is obtained at addition of 8 gram PEG 6000 to MgFe 2 O 4 , with coercivity, saturation, and remanence are 198.41 Oe, 52.53 emu/g, and 8.51 emu/g, respectively. So that, the sample is widely used as absorbance material of heavy metal.
