What Is Ferric Ammonium Sulfate? Formula and Practical Uses
Ferric ammonium sulfate is a chemical compound made from iron, ammonium, and sulfate ions. Its formula is FeNH4(SO4)2. Usually, it appears as brownish-red crystals that dissolve well in water. Its stability depends on the pH of the environment.
What Is It Used For?
| Field | Usage and Examples |
|---|---|
| Medicine | Used to produce antibiotics and iron supplements. For example, ferric ammonium sulfate helps stabilize iron in medicines treating anemia. |
| Water Treatment | Applied as a coagulant to remove suspended particles in wastewater. Municipal plants use it to clarify water before release or reuse. |
| Mining | Helps extract metals like gold and antimony from ores. For instance, gold mining companies add ferric ammonium sulfate to improve metal recovery rates. |
| Fertilizers | Added to organic fertilizers to supply plants with iron. Iron-deficient soils benefit from fertilizers containing this compound, improving crop yield. |
| Fire Safety | Used in flame retardants applied on textiles and plastics to reduce flammability in buildings and vehicles. |
| Photography | In traditional photography, it reacts with silver salts to develop photographic films and papers. |
Handling and Safety
Ferric ammonium sulfate should be stored in a dry place. Avoid inhaling dust or letting it contact skin for long periods. Wearing gloves and masks is recommended during handling.
