A method for forming a magnetic hydrochar nanocomposite includes the step of adding basically treated desert date seeds into a vessel containing phosphoric acid and mixing the basically treated desert date seeds with the phosphoric acid to form a mixture. The mixture is transferred to a microwave and heated to 150° C. The mixture is held at this temperature for one hour to form a hydrochar. The magnetic hydrochar nanocomposite is further formed by dissolving ferrous sulphate and ferric chloride to form magnetic nanoparticles. The magnetic nanoparticles are mixed with the hydrochar, then date fruit extract is mixed with the magnetic nanoparticles and hydrochar mixture to form a resultant mixture. The pH of the resultant mixture is raised to 9-11 by adding sodium hydroxide to form a basic resultant mixture. The basic resultant mixture is heated in a microwave to 150° C. for 30 minutes to form the magnetic hydrochar nanocomposite.
