ABSTRACT
Methylene blue, a synthetic dye is widely used in the textile industry. Methylene blue has a negative impact on the environment, for example contaminated water, so it is necessary to overcome this problem, using degradation method. This research has been carried out on the application of iron oxide nanoparticles for the degradation of methylene blue. Iron oxide nanoparticles were prepared using ball milling method based on Logas natural sand Kuantan Singingi Regency, Riau Province. The product of ball milling (iron oxide powder) was divided into 5 parts with the same amount of weight namely BM3A, BM 3B, BM3C, and BM3E. These products were doped using cobalt with concentration of 0, 5, 10, and 20 wt.% using ball milling. Magnetic and morphological properties of the sample were determined using Vibrating Sample Magnetometer (VSM) and Scanning Electron Microscope (SEM), respectively. The VSM results showed that the values of saturation magnetization (Ms), remanent magnetization (Mr) and coercivity (Hc) increased with the addition of Cobalt concentration. The saturation Magnetization value (Ms) is 7.98 emu/g; 17.42 emu/g; and 19.01 emu/g, Remanent magnetization (Mr) 0.65 emu/g; 1.52 emu/g; and 1.64 emu/g, Coercivity (Hc) 124.21 Oe; 255.5 Oe; and 269.29 Oe with cobalt concentration of 0, 10 and 20 wt.%, respectively. The SEM measurement results for the magnification of 10,000 times showed a decrease in the average particle size as the concentration of Cobalt doping increased, namely 0.812 μm; 0.637μm; and 0.631 μm. The ability of Iron Oxide nanoparticles as a catalyst in UV-Vis spectroscopy and showed a decrease ability to degrade methylene blue in aqueous solution when Iron Oxide nanoparticles are doped with Cobalt with concentration of 10 and 20 wt.%.. The best efficiency is when they are doped with Cobalt 0 wt.%, 5 wt.% and 10 wt.% in the first 20 minutes that 81.62%, 70.909% and 82.856% respectively.
