Aplikasi Nanopartikel Hematie Didoping Dengan Mangan Untuk Adsorpsi Logam Berat Di Air Sungai Siak

ABSTRACT
Water pollution by heavy metals is a serious problem in human life and the lives of other living things in particular. The method that can be used is adsorption with Magnetic Nanoparticles. Magnetic nanoparticles were prepared from natural sand in Logas Village, Kuansing Regency using ball milling for 120 hours. The product from ball milling obtained was divided into 3 parts and then doped using Manganese (Mn) with concentrations of 0 wt% (without doping), 5 wt%, and 10 wt% of the total mass weight of the ball milling product. Nanocomposite (α-Fe2O3 +Mn) was used to absorb some heavy metals such as Pb and Cu in Siak River water. Siak river water samples were taken around the water flow under the Siak I Bridge, Pekanbaru. Magnetic susceptibility was measured using the Pasco PS-2126 Magnetic Probe. The crystal size and magnetic phase of the product were determined using the X-Ray Diffraction (XRD) method. The amount of heavy metal adsorption was determined using Atomic Absorption Spectroscopy (AAS). XRD characterization results showed that the crystal size decreased with increasing manganese (Mn) concentration. In addition, the sample consists of Hematite (α-Fe2O3). The results of AAS characterization showed that the amount of heavy metals in water decreased with increasing manganese (Mn) concentration.
Keywords: Adsorption, Doping, Heavy Metals, Magnetic Nanoparticles, Manganese(Mn)
