Zerovalent iron (ZVI) is jargon[clarification needed] that describes forms of iron metal that are proposed for use in groundwater remediation.
[1][2][3][4] ZVI operates by electron transfer from Fe0 toward some organochlorine compounds, a common class of pollutants.
The remediation process is proposed to generate Fe2+ and Cl− and halide-free organic products, all of which are relatively innocuous.
[5] Nanoscale ZVIs (nZVIs) are commonly used in remediation of chlorinated compounds and other pollutants.
[6] Treatment of many kinds of pollutants has been proposed, but few have been demonstrated in solving environmental challenges.
