Abstract: A fabrication method for magnetic nano complex with a nanoparticle/polymer core-shell structure for a heavy metal adsorbent is provided to facilitate a manufacturing process of a core-shell complex with uniform sizes and thickness of a shell regardless of kinds of polymer. A fabrication method for magnetic nano complex with a nanoparticle/polymer core-shell structure comprises the following steps of: dispersing magnetic nanoparticles in an aqueous solution containing a stabilizer; inputting monomers into the aqueous solution; melting a surface of the magnetic nanoparticle by adding an acid solution to produce iron ions so that the monomers are polymerized on the surface of the magnetic nanoparticle; and collecting the produced magnetic nano complex with a nanoparticle/polymer core-shell structure using magnets.
