Iron(III) Hydroxide (Ferric Hydroxide)
Ferric hydroxide granular is available in two phases Fe(OH₃) and ß-FeOOH.
Please note: Ferric hydroxide slurry is not a stocked product; 2 – 3 weeks lead time is necessary for production. The slurry will discolor over time and separate since Ferric hydroxide is not soluble in water and must be mixed very well before use.
Formula = Fe(OH)₃
Assay = ~13% (Min: 12.5%, Max: 13.5%)
Appearance = Chocolate brown
Free Acid = 0.00%
Iron = ~6.81% (Min: 6.54%, Max: 7.07%)
Ferric hydroxide is used as a water purification treatment to remove arsenic and other heavy metals from contaminated sources. It can be used in wastewater, drinking water treatment, and mineral and table water production. It can also treat natural water and roof and street runoff water.
Industrial uses include manufacturing pigments, including rubber pigments, as a catalyst, and in nuclear waste irradiation.
Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers.
