Magnetic iron oxide nanoparticles are attractive to many researchers because of their wide ranging applications viz. data storage, magnetic fluids, adsorbent, catalysis, biotechnology, biomedicine and environmental remediation. In the present study, efforts have been made to develop magnetic iron oxide nanoparticles activated carbon composite (MIONAC). The activated carbon is prepared from corncob using zinc chloride as an activating agent in a modified muffle furnace with N2-gas inflow arrangement and magnetic nanoparticles by chemical co-precipitation method. The prepared corncob activated carbon (CCAC) and Magnetic iron oxide nanoparticles activated carbon composite (MIONAC) are characterized for N2-BET surface area, SEM, FT-IR, XRD, TEM, pHpzc and VSM. The N2-BET surface area of the MIONAC (807 m2g-1) is found lesser than the prepared CCAC (1429 m2g-1). MIONAC exhibits super magnetic properties under external magnetic field with saturation magnetization value 4.15 emu/g at room temperature. SEM of the CCAC and MIONAC shows the presence of cracks and crevices. TEM of MIONAC shows nanoparticles with size in between 10-20 nm. A broad peak at 2&
