Groundwater Remediation

Reductive Technologies Based on Nanoscale Zero-valent Iron

Highly efficient in removal of

  • Inorganic compounds like Arsenic, Barium, Chromium, Selenium, Uranium, Copper, Lead, Cadmium, Mercury, Nickel (and many other heavy metals), sulphates, nitrates,perchlorates, etc.
  • Organic compounds like polychlorinated methanes, ethanes, ethenes, benzenes, etc

Properties of fe0 nanoparticles

  • High redox potential (electron donor)
  • High surface area (20-25 m2/g)
  • Narrow particle size distribution (average of 50 nm) allowing the particles to migrate in groundwater conditions
  • Pyrophoric or air-stable character (powder or aqueous dispersion)
  • Magnetically separable
  • High-reactivity and long-term performance
  • Possibility to combine various properties in composite materials
  • Ideal for remediation of large areas or for construction of permeable reactive barriers
  • Environmentally friendly material
  • Low cost comparing to conventional technologies

Application example

In field application of the reductive barrier at MaRS SVRATKA (czech republic) in 2012-2014)

Concentration of CIE day 0

Concentration of CIE day 180

Available products


  • Fe0 nanoparticles (powder) without surface modification
  • Highly reactive and pyrophoric Fe0 nanoparticles


  • Aqueous dispersion of Fe0 nanoparticles modified by biodegradable organic stabilizer
  • Highly reactive with large scale of pollutants
  • Excellent migration properties


  • Surface-stabilized Fe0 nanoparticles (powder)
  • Safe storage, transport, handling and applications compared to non-stabilized Fe0 nanoparticles
  • When activated, the Fe0 nanoparticles are highly reactive with reducible pollutants
  • Possibility to combine with biodegradable organic stabilizer for better migration performance

Fe0-based composites

  • Micro-Fe0 & nano-Fe0 composite material combining long-term reactivity of microparticles with rapid effect of nanoparticles
  • Nano-Fe0 & carbon composite material combining reductive/magnetic properties of Fe0 nanoparticles with sorption properties of carbon (active carbon, carbon black, nanotubes, biochar etc.)
