synthesis and characterization of magnetic activated carbon developed from waste oil flaxseed

Magnetic activated carbon (MG-AC), a solid product made by dispersing magnetic substrates on AC, is gaining attention for the removal of heavy metals and Medicinal pollutants from wastewater due to its favorable physico-chemical properties such as enhanced surface area and magnetic properties, respectively. However, the effects of two contrasting substrates, i.e., metal solution and metal particles, for the synthesis of MG-AC to obtain enhanced magnetic property have not been considered.Preparation of the AC was performed in two steps: activation by traditional methods and carbonization. Preparation of the Fe-Ac adsorbent:FeSO4.7H2O and FeCl3.7H2O solution were added into a 400ml beaker and heated were added to 363 k° 3.3 gr of AC was weighted and added to the mixture. 100 ml of 5 mol/lit NaOH was added drop-wise for 5 min and the Iron Oxide in the mixture was precipitated. The adsorbent samples were characterized using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission Electron Microscope (TEM), energy-dispersive X-ray, nitrogen adsorption, vibrating sample magnetometer(VSM).
