Abstract Currently, the thorny issue is treated wastewater in the lakes and rivers where it is near industrial companies and residential areas. This study contributed to the synthesis of magnetic carbon nanospheres (MCNs) which had been recovered the heavy metals and organic contaminants by a magnet. This research synthesized MCNs through three different routes. (1) MCNs was synthesized by iron-polydopamine (Fe-PDA) complex and the surface functionalization of MCNs, which helps to capture the heavy metals and organic pollutants, was altered by hydrogen peroxide. (2) The second route was used two-steps synthetic. The first step was a synthesis of iron oxide (Fe3O4) and the second step was coating polydopamine (PDA). (3) The final route synthesized MCNs through integration between the iron compound and carbon nanospheres (CNS). And the surface modification was adjusted similarly the first route. The physical and chemical properties of MCNs were assessed by performing infrared spectroscopy (IR spectroscopy), dynamic light scattering (DLS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area and Zeta potential. Especially, MCNs via route (3) synthetic was well-dispersed and uniformly which was proved by TEM images. Moreover, the functional groups were demonstrated by IR spectroscopy. MCNs was modified surface that it is potentially utilized as sorbents for the heavy metals and organic contaminants. Further research is required to determine the concentration of the heavy metals and organic pollutants, which are removed by MCNs, through inductively coupled plasma mass spectroscopy (ICP-MS).
