Long-term performance of milled zerovalent iron particles for in situ groundwater remediation

Abstract

International audienceThe nanoscale zerovalent iron (nZVI) particles are widely used with high success in removal/degradation of a variety of environmental contaminants under laboratory conditions. However, high production costs, mobility of nZVI particles limited to a maximum of a few meters due to the rapid aggregation of primary particles, and limited effectiveness of the iron surface to serve as an electron donor for longer period due to fast depletion of nZVI particles after side reaction with groundwater constituents were main technical obstacles for rising the full potential of this technology
