The Fe3O4 nanoparticles were synthesized from natural iron sand by dissolving it in HCl and precipitated by NaOH. Two solutions of iron rocks were treated, one without starch and one with starch, followed by NaOH. Both samples were characterized by X-ray Diffractometer (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FT-IR), and Energy Dispersive X-ray (EDX) to record the crystallinity, morphology, and coating of starch on the Fe3O4 surface. The XRD pattern shows the presence of crystalline structures between bare and coated magnetic particles. SEM shows its morphological structure. EDX shows the elemental composition Fe present up to 75% in rocks. The removal of methyl orange dye is investigated and found 75% removal efficiency at the optimum condition at pH 6 at 120 minutes.
