Ammonium Sulphate

Ammonium Sulphate (AS) is an inorganic salt with the chemical formula (NH₄)₂SO₄. It is widely used as a fertilizer and soil conditioner due to its high nitrogen and sulfur content, which are essential nutrients for plant growth. Ammonium Sulphate appears as a white or off-white crystalline solid, odorless, and soluble in water. It is a stable compound under normal conditions and non-flammable.

Applications:

1. Agriculture:
   • Fertilizer: Commonly used as a nitrogen fertilizer, particularly beneficial for crops that require additional sulfur, such as canola, soybeans, and potatoes.
   • Soil Conditioner: Helps lower soil pH in alkaline soils, improving nutrient availability for plants.
   • Blending: Often used in fertilizer blends to supply both nitrogen and sulfur to crops.
2. Food Industry:
   • Used as a food additive in the preparation of bread and other bakery products to improve dough quality.
3. Industrial Applications:
   • Utilized in the production of ammonium alum and in the treatment of water for coagulation.
   • Employed in the textile industry for dyeing and printing fabrics.
4. Laboratory Use:
   • Applied in protein purification processes as a precipitant to isolate and concentrate proteins.

Handling and Storage:

• Handling:
  • Avoid inhalation of dust and contact with skin and eyes.
  • Use appropriate personal protective equipment (PPE) such as gloves, goggles, and protective clothing.
  • Ensure good ventilation to avoid the buildup of dust, which may cause respiratory irritation.
  • Handle with care to prevent the formation of dust and minimize exposure.
• Storage:
  • Store in a cool, dry, and well-ventilated area away from moisture and incompatible materials.
  • Keep the container tightly closed to prevent caking and contamination.
  • Store away from strong acids, bases, and oxidizing agents.
  • Ensure proper labeling and store in original packaging to maintain product integrity.

Safety Considerations:

• Hazard Statements: Ammonium Sulphate is generally safe, but prolonged exposure can cause irritation to the eyes, skin, and respiratory system. Dust inhalation may lead to respiratory discomfort.
• First Aid Measures: In case of contact with skin or eyes, rinse immediately with plenty of water. If inhaled, move to fresh air and seek medical attention if symptoms persist.
