Progress of Removing Heavy Metals by Zero Valent Iron Nanoparticles from Wastewater

Abstract:

Heavy metal pollution is a serious threat to human health. Because of the development of nanotechnology, removal of heavy metal is more convenient and effective. nanozero valent iron (Fe⁰) particles have high activity and specific surface area. At present, Fe⁰ nanoparticles have been used in the processing of refractory organics, heavy metals, inorganic salts, soil restoration, and other areas of the environment. But the dispersion and stability of the Fe⁰ nanoparticles are poor. We can improve physical and chemical properties of Fe⁰ by adding carrier materials to make iron nanoparticles have better stability, dispersion and the treatment effect. This paper mainly introduced the situation of removing heavy metals by the Fe⁰ nanoparticles and hybridized Fe⁰ particles. Hybridized Fe⁰ has good performance and high removal efficiency to heavy metals. We also discussed what are inadequate and need to be further researched.
