Abstract In this work, magnetite loaded poly(sulfur/oil) (MLP(S/O)) composite super hydrophobic polymer has been prepared by allowing reaction between sulfur powder and edible oil in the presence of magnetite nano particles. The magnetite particles, with 68 % of the particles in the range of 5–10 nm, were characterized by TEM and SAED analysis. The MLP(S/O) material was also characterized by FTIR, XRD, TGA/DTA, EDS and SEM analysis. The M-H curves were also obtained for the adsorbent material MLP(S/O), taking native magnetite nanoparticles as control. It was found that the composite MLP(S/O) possessed fair magnetization. The saturation magnetization MS for the native magnetite and the MLP(S/O) composite were found to be 27.889 and 7.996 emu/g respectively. In addition, the Remanent Magnetization (MR), for the samples magnetite powder and MLP(S/O) composite were found to be 0.172 and 0.0199 emu/g respectively. Finally, the MLP(S/O) material was used as adsorbent to remove oil from water and the oil-adsorbed MLP(S/O) was removed from the adsorption system by using a bar magnet with moderate strength.
