Ammonium sulfate is a white, crystalline solid commonly used as a nitrogen-rich fertilizer in agriculture. It helps improve soil nitrogen content and promotes plant growth, especially in alkaline soils. Apart from fertilizers, it is also used in water treatment, food processing as a dough conditioner, and in various industrial applications like flame retardants and textiles.

Industrial Uses

1. Agrochemicals

  • Nitrogen Fertilizer: It is a slow-releasing nitrogenous fertilizer, providing plants with the nitrogen they need for growth, particularly in soil with alkaline pH.
  • Sulfur Source: It also acts as a source of sulfur, a macronutrient that is essential for plant health and development.

2. Water treatment

  • Coagulant and Flocculant: It helps bind and remove suspended particles from water, making them easier to filter out during sedimentation and filtration.
  • Disinfectant: Ammonium sulfate, containing ammonium ions, reacts with chlorine (often in the form of sodium hypochlorite) to form monochloramine. Monochloramine is used as a secondary disinfectant, meaning it's added to the water distribution system after the initial disinfection process.

3. Food & healthcare ingredients

  • Acidity Regulator: In flours and breads, ammonium sulfate helps to control the pH level, which is important for proper dough development and fermentation.
  • Dough Conditioner: It acts as a dough conditioner, enhancing the texture and flavor of baked goods by improving gluten development and dough stability.

4. Pharmaceuticals

  • Protein Purification: Ammonium sulfate precipitation is a common method for separating and purifying proteins from complex mixtures. By increasing the ionic strength of a solution, ammonium sulfate reduces the solubility of proteins, causing them to precipitate out of solution. This allows for the selective removal of proteins based on their solubility characteristics, making it a valuable tool in biopharmaceutical manufacturing.

5. Fabric solutions

  • Leveling Agent: It helps to prevent blotchy or uneven dyeing by slowing down the rate at which dyes are absorbed into the fabric. This allows for more even distribution of the dye molecules, resulting in a more uniform color.
  • Dye Penetration Enhancer: By slowing down the dye absorption, ammonium sulfate allows the dye to penetrate more deeply into the fibers, leading to a more vibrant and durable color.
  • Acid Dyestuffs: It is particularly useful in dyeing with acid dyestuffs, especially on protein fibers like wool and silk.
