Daftar Isi:
- Have conducted studies looking at the effect of PEG -2000 to measure Fe3O particles were synthesized by coprecipitation method. Magnetic iron sand obtained from the processing of iron rock. Iron sand is then treated with HCl and NH 4 4 OH using coprecipitation method. Variation used is iron sand with no PEG 2000, iron sand PEG -2000 (1:1), iron sand with PEG -2000 (1:2) and iron sand with PEG -2000 (1:4). XRD characterization produce Fe 3O crystal size in a row that is 217,00 nm, 108,75 nm, 81,57 nm and 130,02 nm . Based on the results of SEM shows that the cuboid Fe 3O44 particles with particle size decreased from 80,00 to 220.00 nm to 60.00 to 127,50 nm with increasing concentrations of PEG -2000.
