1. A process for preparing an iron oxide nanocomposite, the process comprising:

preparing a date palm charcoal powder;

adding the date palm charcoal powder and ferric nitrate to ethylene glycol and optionally other 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 iron oxide nanocomposite.
