  • Applications

    Ammonium ferric sulfate dodecahydrate (CAS 7783-83-7) is used in practice with applications including as a fixative or mordant for dyeing and printing on textiles; as a coagulant aid in water and wastewater treatment to remove suspended solids and color; as a source of Fe3+ ions for analytical chemistry and laboratory applications; and it may be evaluated for coatings and inks to improve pigment adhesion.
