Aplikasi Nanopartikel Magnetik Didoping Dengan Mn Untuk Adsorpsi Logam Berat Dalam Air Sungai Siak

---

The 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).
