of iron oxide

Fix-All safely and readily absorbs and insolubilizes heavy metals of contaminated soil and water in pH neutral conditions, thereby reducing the diffusion of environmental contamination.

Chief components

  • Fe2O3·nH2O
  • CaSO4·nH2O
Specific surface area of iron oxide 180m²/g or more

Intended use

  • Mainly used for four elements: arsenic, selenium, lead and cadmium.
  • Also used for cleaning up mercury, hexavalent chromium and fluorine.
