Effects of Nano Zero-Valent Iron on Oxidation−Reduction Potential
Environmental Science & Technology, 2011 Oxidation-reduction potential (ORP) measurements have been widely used to assess the results of injection of nano zerovalent iron (nZVI) for groundwater remediation, but the significance of these measurements has never been established. Using rotating disk electrodes (RDE) in suspensions of nZVI, we found the electrode response to be highly complex but

Annals of Warsaw University of Life Sciences - SGGW. Land Reclamation, 2014 Abstract Hydraulic performance of zero-valent iron and nano-sized zero-valent iron permeable reactive barriers - laboratory test. The hydraulic conductivity of zero-valent iron treatment zone of permeable reactive barriers (PRBs) may be decreased by reducing the porosity caused by gas production and solids precipitation.
