REUSABLE HEAVY METAL ELIMINATING AGENT AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF SEPARATING HEAVY METALS FROM A HEAVY METAL ELIMINATING AGENT AND REUSING THE SEPARATED HEAVY METALS
REUSABLE HEAVY METAL ELIMINATING AGENT AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF SEPARATING HEAVY METALS FROM A HEAVY METAL ELIMINATING AGENT AND REUSING THE SEPARATED HEAVY METALS
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.;COPYRIGHT KIPO 2012
