Wastes of  paper industry was used as alternative raw material to non-renewable carbon sources to produce activated carbon  to produce a nanocomposite to remove two drug namely Gentamycine and Diclofenac via adsorption process. The synthesis of Magnetic iron-oxide activated carbons  was performed by in-situ co-precipitation of magnetic iron oxides to AC. The physicochemical properties of the nanocomposite was investigated with XRD and FTIR analysis. For maximum Gentamycine and Diclofenac adsorption yields (99% and 98%) the optimal contacting time, Magnetic iron-oxide activated carbon composite concentration and Gentamycine and Diclofenac concentrations were 10 min., 2 mg/l and 500 mg/l and 780 mg/l, respectively. The adsorption of both drugs exhibited good suitability with Langmuir fittings showed that qm were 225 and 480 mol g− 1 , for Gentamycine and Diclofenac, respectively
