The synthesis of magnetic nanoparticles from naturaliron sand of Kata beach Pariaman West Sumatera using ball milling method as environmental material

Abstract

Synthesis, magnetic, and structural properties and adsorption study of magnetic particles of Fe3O4 have 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 Fe3O4 has 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.

Magnetic hydrogel applications in articular cartilage tissue engineering

“…In this method, produced nanoparticles are not uniform, usually do not show proper magnetism characteristics, and have a broad particle size distribution. 110 Although physical strategies such as Ball Milling, 111 they require the use of expensive laboratory equipment. Chemical methods such as Sol-gel, Solvothermal, Co-precipitation, and Thermal decomposition are used to design highly monodisperse MNPs with a well-controlled magnetic response.…”

Review of Magnetic Fluids and their Applications to Vibration Reduction

“…Since the advent of the ball milling method, scholars have also been continuously improved, Hong Ruoyu [25] and others proposed to first use the co-precipitation method to synthesize the particles, and then put into the ball mill, after that add surfactant for ball grinding, and obtained a water-based MFs with good temperature resistance and dilution resistance. Some scientists have found that increasing the time of ball milling can improve the properties of magnetic fluids [26].…”
