Nanometer Zero-Valent Iron (nZVI) is a highly reactive form of iron that is used for environmental remediation, particularly for the treatment of contaminated soil and groundwater. The nanoscale size of nZVI particles significantly enhances their reactivity and surface area, making them effective for a variety of environmental applications.

nZVI consists of iron particles typically less than 100 nanometers in size. At this scale, iron exhibits unique properties, including increased reactivity and enhanced ability to interact with contaminants. Zero-valent iron (Fe^0) means the iron is in its metallic form, which is highly reactive and can donate electrons to various contaminants, reducing them to less harmful forms.

Key Properties

High Reactivity: The large surface area to volume ratio of nZVI particles increases their reactivity compared to larger iron particles.
Versatility: nZVI can treat a wide range of contaminants, including chlorinated solvents, heavy metals, and certain organic compounds.
Mobility: The small size of nZVI allows it to penetrate and treat contaminated sites more effectively than bulk iron particles.
