Preparation and Characterization of Magnetic Coal-Based Activated Carbon in the Presence of Fe₃O₄

Abstract:

Magnetic coal-based activated carbon was prepared from Taixi anthracitic coal in the presence of magnetite (Fe₃O₄). The magnetic activated carbon samples were characterized by N2 adsorption, XRD, FTIR and vibrating sample magnetometer (VSM). It was found that the magnetic activated carbon had a high surface area of 993.5 m²/g with 4% Fe₃O₄and a saturation magnetization of 2.4158 emu/g for magnetic separability. The results showed that the magnetic properties of MAC are provided by Fe₃O₄and Fe. In the presence of Fe₃O₄, the rate of carbonization and activation increase to form a large surface area and a high pore volume. Moreover, the addition of Fe₃O₄ can greatly promote the number of both micro-pores and meso-pores in activated carbon.
