Herein, we report the synthesis, characterization and adsorption (copper and methy testosterone (MT)) studies of iron oxide (Fe3O4), carbon nanotubes (CNTs) and reduced graphene oxide (r-GO) composites. To prepare the composite, firstly, the Fe3O4/CNTs (M-Fe3O4) composites were prepared through a pyrolytic process followed by the formation of r-GO/M-Fe3O4 composite by decomposition and reduction method. The prepared r-GO/M-Fe3O4 composite were characterized by several techniques such as X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). Finally, the prepared r-GO/M-Fe3O4 composite was used to adsorb copper ions and methyl testosterone (MT) in wastewater. The detailed adsorption studies confirmed that the prepared nanocomposite efficiently adsorb copper ion from waste water. Further, by comparing r-GO/M-Fe3O4 with Fe3O4, it was observed that MT can adsorb similar to 90% from waste water while Fe3O4 can only adsorb only 10% of the MT in the solution.
