Sintesis Dan Karakterisasi Nanopartikel Oksida Besi Menggunakan Metode Ball Milling Dan Kopresipitasi

---

This Research has carried out on natural sand originating from the Rokan river, Riau Province by converting it into magnetic iron oxide nanoparticles to determine changes in magnetic properties and particle size. Natural sand samples of the Rokan river were separated between magnetic and non-magnetic particles using an Iron Sand Separator (ISS). ISS products are further synthesized using ball milling and coprecipitation methods. 70-hour ball milling products, co-compression without ball milling and co-oppitation with ball milling are then given NdFeB (Neodymium Iron Boron) magnets to clean impurities containing non-magnetic elements. The results of this study showed that the highest magnetic acceptability value was obtained in coprecipitation products with ball milling, which was 12.9 x 10-2. This is because coprecipitation products have an abundant content of chemicals in the form of magnetic elements. Based on the results of chemical composition testing using X-Ray Flourescence (XRF) it was found that in coprecipitation products with ball milling there was 64.504% Iron (Fe) content, while 70-hour ball milling products and coprecipitation without ball milling the percentage of Fe protection was 15.023% and 54.152%, respectively. The results of the analysis using ImageJ software in the scanning electron microscope (SEM) results show particles in 70-hour ball milling products measuring 255,227 nm, coprecipitation products without ball milling measuring 238,7817 nm and coprecipitation products with ball milling measuring 104,9683 nm. Based on the particle size changes obtained, coprecipitation products with ball milling have a higher degree of particle size homogeneity.
