Abstract: PURPOSE: A polyphenol-coated nano-scale zero valent iron(P-nZVI) for restoring soil and underground water and a method for preparing the same are provided to expand the effective radius of the P-nZVI by including the superior dispersibility and the mobility. CONSTITUTION: A method for preparing P-nZVI includes the following: polyphenol is added to an iron-contained solution to obtain a polyphenol-Fe solution. A reducing agent is added to the polyphenol-Fe solution. A reaction is implemented to synthesize the P-nZVI. The adding amount of the polyphenol is 10 to 50 parts by weight with respect to 100 parts by weight of iron.
