Abstract :

In this study, we present a novel method to prepare magnetic nano-material based on superparamagnetic iron oxide nanoparticles functionalized with natural surfactants, which can be used to recovery oil from water. The coated magnetite materials are inherently hydrophobic and oleophobic, but they can be rendered water-repellent and oil-absorbing. In this respect, the present work aims to prepare highly dispersed coated magnetite nanoparticles from Fe3+ having small particle size (5-25 nm) and have super paramagnetic properties. The used natural materials based on rosin, fatty acid and acrylamide polymers as coats for magnetite particles to control dispersabilities in aqueous and non-aqueous fluids, particle size and magnetism of the nano-powder materials. The possibility of recycling the beads and reclaiming the oil is also demonstrated. These materials show high performance as oil spill collector for both light and heavy crude oil at different thickness. The synthesized nanostructure consisting of coated magnetite could be used as a pollutant remedy because of its ability to adsorbing crude oil and it is maneuverable under an applied magnetism. In this work a simple undergraduate laboratory experiment to produce magnetic adsorbents is described. The high partitioning of these materials between water and oil assist to enhance crude oil productivity due to their ability to affect the reservoir rocks. Detailed microscopic and wettability studies reveal that the combined effects of the surface morphology and of the chemistry of the functionalized magnetite greatly affect the oilabsorption dynamics. In particular, nanoparticle capping molecules are found to play a major role in this mechanism.
