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. Nanoscale ZVIs (nZVIs) are commonly used in remediation of chlorinated compounds and other pollutants.
