Abstract
The application of nanotechnology in drinking water treatment and pollution cleanup is promising, as demonstrated by a number of field-based (pilot and full scale) and bench scale studies. In recent years, the use of zero-valent iron (ZVI) for the treatment of toxic contaminants in groundwater and wastewater has received wide attention and encouraging treatment efficiencies have been documented. In this review, nanoscale iron was prepared by pulse electrodeposition of nano iron by chemical reduction of iron chloride and iron sulfate. Our research focuses on iron nanoparticles preparation and its use for aqueous Cr(VI) reduction. The Cr(VI) reduction by the nFe 0 prepared by electrochemical and blasting method at neutral pH were carried. The results show that blasting-nFe 0 show lower reaction than the electrochemical-nFe 0 . It is because the blasting-nFe 0 surface contains more Fe 2 O 3 than the other one.
