Abstract
Synthesis, magnetic, and structural properties and adsorption study of magnetic particles of Fe3O4have been carried out. Magnetic particles were synthesized from natural iron sand of Kata Beach Pariaman West Sumatera using ball milling method. The structural properties of the samples were determined using X-Ray Diffractometer (XRD) technique. Magnetic properties such as magnetization were measured based on hysteresis loop using vibrating sample magnetometer (VSM). Mass susceptibility of the sample was measured using Pasco magnetic probe. It was found that the mass susceptibility of magnetic particles increased significantly as ball milling time increased. Based on VSM results, the magnetic particle of Fe3O4has magnetization value of 32.26 emu/g with small coercivity of 174 Oe. Moreover, the results showed that ball milling method has succeeded to obtain magnetic particles. The increase of ball milling time resulted in an increase of magnetic moment of the sample. In this research, the magnetic particle of Fe3O4 was added to a solution of methyline blue performed using shaker method. Atomic Adsorption Spectroscopy (AAS) method was used to study the methylene blue degradation.

Summary
The synthesis of magnetic nanoparticles from iron sand has attracted great attention in the last years because of new physical and chemical properties of materials at the nanoscale. Ball milling method is a simple and efficient method in crunching the iron sand concentrate in a rotating tube using metallic or ceramic balls. Previous researchers [16, 17] have used this method to synthesize magnetic nanoparticles from the iron salt precursor. They found that the size of magnetic nanoparticles is around 10-15 nm. They found that magnetic nanoparticles that synthesize using ball milling resulted in higher magnetic saturation (14 emu/gr) compared to that of using a chemical method that gives magnetic saturation value of 3 emu/gr. We report the magnetic, structural properties of magnetic nanoparticles synthesized using ball milling method and state of the art uses of magnetic nanoparticles to study the methylene blue degradation
