摘要： A heavy metal remover of a core-shell structure comprises a core including carbon nanotubes (CNT) that can aggregate and scatter in a reversible manner, and a shell including iron oxide. A method for fabricating a heavy metal remover of a core-shell structure comprises (a) preparing a carbon nanotube (CNT) aqueous solution where acid-treated CNTs have dissolved, (b) mixing the CNT aqueous solution with an aqueous solution of polymer template particles, thereby forming a CNT layer on the surface of the template particles, (c) mixing the solution having undergone the step (b) with a polymer electrolyte having positive charges, thereby forming a polymer layer on an outer surface of the CNT layer, (d) adding FeSO4, Fe2(SO4)3 or a mixture thereof to the solution having undergone the step (c), and stirring the solution, thereby including iron oxide in the polymer layer, (e) separating particles from the solution having undergone the step (d), and (f) removing the template particles by heat-treating the particles having been separated in the step (e). The method for removing heavy metal ions is capable of removing heavy metal ions by adsorbing the heavy metal ions into the CNTs of the core, with using the heavy metal remover of a core-shell structure.
