Nanometer zero-valent iron (nZVI) technology is one of the hotspot in environmental science, according to its huge surface area and high reactivity for the heavy metals, halogenated organic matter. However, as a result of a single nZVI problems easy to reunite and oxidized effect of nZVI reactivity, reduction of pollutant removal effect, the modification of nanometer zero-valent iron is a hotspot of nZVI technology this paper mainly discusses the conventional physical and chemical preparation methods of nanometer zero-valent iron and modified nano zero-valent iron technology are summarized, the future research emphases of nZVI technology are prospected.
Keywords: nZVI preparation method modification
