Small size of the iron nanoparticles due to effective and facilitate distribution of their subsurface and also their large surface area due to high reactivity of nano particles and rapid degradation of pollutants. Nano particles can act as Catalyst reducing agent in the detoxification of many environmental pollutants such as solvents, chlorinated organic pesticides, polychlorinated biphenyls, heavy metals (Cr, Pb), arsenic, nitrate, and ... . Iron nanoparticles are used for decomposition of Chlorinated hydrocarbons such as trichloromethane, perchloroethylene and carbon tetrachloride. These compounds are the most important soil and ground water pollutants. The goal of this study is argument about the method of synthesis and nomination of iron nanoparticles and its applications for the removal of halogenated organic pollutants, heavy metals, dechlorination of colorful compounds, herbicides and insecticides analysis in watery sources.
