Abstract: The magnetic adsorbent for organic pollution removal is an adsorbent material, preferably in the form of microcapsules, for adsorbing organic pollutants, such as methylene blue, onto the microcapsules from contaminated water. Each of the magnetic adsorbent microcapsules is formed from magnetic iron oxide (Fe3O4) particles embedded in a nitrogen-enriched porous carbon matrix. To make the magnetic adsorbent microcapsules, urea and formaldehyde are mixed to form a pre-polymer solution. Magnetic Fe3O4 is mixed with an aqueous epoxy resin in hexane to form a mixture, which is then sonicated and added to the pre-polymer solution to form a polymeric solution. A surfactant, such as sodium lauryl sulfate, is added to the polymeric solution to form a suspension of magnetic microcapsules. The magnetic microcapsules are washed, filtered and dried before annealing in a tube furnace to form the adsorbent microcapsules, which are then washed and dried.
