REUSEABLE HEAVY METAL REMOVER AND THE FABRICATION METHOD THEREOF

摘要

PURPOSE: A reusable heavy metal eliminating agent and a method for manufacturing the same are provided to effectively eliminate heavy metals using an heavy metal eliminating agent of a core-shell structure. CONSTITUTION: A carbon nano-tube aqueous solution is prepared by dissolving acid-treated carbon nano-tubes. The carbon nano-tube aqueous solution is mixed with a polymer template particle aqueous solution to form a carbon nano-tube layer on the surface of template particles. The solution through the previous processes is mixed with a polymer electrolyte of a positive electric charge to form a polymer layer on the external side of the carbon nano-tube layer. FeSO_4, Fe_2(SO_4)_3, or the mixture of the same are added to the solution through the previous process and is stirred such that the polymer layer includes iron oxide. Particles are separated, and the template particles are eliminated by a thermal treating process.
