dc.description.abstractThe magnetic nanoparticles were prepared from River Suci Bengkulu beach sand using two-stage ball milling for 120 hours. The product of the ball milling was divided into 3 parts and then doped using manganese (Mn) with a concentration of (0; 5; and 15)% of the total mass magnetic nanoparticles using ball milling for 20 hours. These nanocomposite (α-Fe2O3/Fe3O4+Mn) were used to adsorb some heavy metals such a lead Pb and Cu in Sungai Siak’s water at Duku Harbor Pekanbaru. The magnetic susceptibility of the samples was measured using Pasco Magnetic Probe PS-2162. The crystallite size and magnetic phase of the product were determined using X-Ray Diffraction (XRD) method. The amount of heavy metal adsorption was determined using Atomic Absorption Spectroscopy (AAS). The XRD characterization results showed that the crystalline size increases with increasing manganese (Mn) concentration. Moreover, the sample consisted two magnetic phase that is Fe3O4 (Magnetite) and α- Fe2O3 (Hematite). The AAS characterization results showed that the amount of heavy metals decreases with the increase in the concentration of manganese (Mn).en_US
