A novel magnetic rice chaff oil absorption material was successfully synthesized by immobilizing Fe3O4 nanoparticles onto rice chaff with the aid of mussel-inspired polydopamine and subsequently chemical modification by octadecylamine with low surface energy. Scanning electron microscope (SEM), infrared spectrometer (FTIR) and X-ray diffraction (XRD) instrument were used to characterize the morphology, crystallinity and functional groups of the obtained magnetic rice chaff. The results indicated the magnetic rice chaff had large water contact angle of 135° and magnetic saturation intensity of 39.6 emu/g. The highest oil absorption of magnetic rice chaff reached 6.83 times of its own weight for chloroform. The prepared magnetic rice chaff oil absorption material with high recyclability could be widely used in large-scale removal of spilled oil from water.
