1. A process for preparing a date palm charcoal iron oxide nanocomposite, the process comprising:
preparing date palm charcoal by heating raw date palm waste in a slow pyrolysis process;
grinding the date palm charcoal to obtain a fine powder of date palm charcoal;
adding the fine powder of date palm charcoal and ferric nitrate to one or more solvents to obtain a mixture;
drying the mixture to obtain a carbon matrix of iron oxide magnetic nanoparticles; and
separating the carbon matrix of iron oxide magnetic nanoparticles from non-magnetic carbon particles to obtain the date palm charcoal iron oxide nanocomposite.
