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).
