PURPOSE: A wastewater refining method using polydopamine is provided to easily regenerate polydopamine silica beads and to remove both organic materials and inorganic materials from wastewater. CONSTITUTION: A wastewater refining method using polydopamine includes the following: polydopamine is coated on a substrate; and the substrate is introduced into wastewater to absorb pollutants. The substrate is selected from a group including silica beads, non-oxidation metals, metal oxides, alkali metals, synthetic polymers, ceramics, and semiconductors. The pollutants are selected from a group including heavy metals, toxic organic materials, and radioactive isotopes. The heavy metals are selected from a group including Cr, Pb, Cd, Hg, Cu, Zn, Co, Ni, Mg, Fe, Mn, and Ca. The toxic organic materials are selected from a group including 4-aminopyridine, 4-methylbenzenethiol, amitrole, starlicide, dicloran, aminopyralid, butylamine, proxan, quinoclamine, thiosemicarbazide, fluoroacetamide, tioclorim, and carbathion. |
