Zero-Valent Iron Nanoparticles for Soil and Groundwater Remediation [PDF]

International Journal of Environmental Research and Public Health, 2020
Zero-valent iron has been reported as a successful remediation agent for environmental issues, being extensively used in soil and groundwater remediation. The use of zero-valent nanoparticles have been arisen as a highly effective method due to the high specific surface area of zero-valent nanoparticles.

Reactivity of Nitrate with Zero-Valent Iron

Water, 2022
Elevated nitrate concentrations in groundwater and surface water supplies can negatively impact the quality of the environment and human health. Recent studies have examined the use of zero-valent iron technology to treat nitrate-contaminated groundwater. Mechanistic aspects of nitrate reduction by zero-valent iron are unresolved.
