Ammonium Persulphate

c(APS) is a white, crystalline, odorless salt with the chemical formula (NH₄)₂S₂O₈. It is a powerful oxidizing agent used in various industrial applications due to its ability to decompose into free radicals. APS is soluble in water and commonly used in the polymerization of monomers, etching and cleaning of printed circuit boards, and other applications where a strong oxidizer is required.

Applications:

1. Polymerization Initiator: Used as a free radical initiator in the polymerization of various monomers like acrylonitrile, styrene, and butadiene.
2. Etching Agent: Employed in the manufacture of printed circuit boards for etching copper.
3. Bleaching Agent: Utilized in the textile and paper industries for bleaching purposes.
4. Cleaning Agent: Applied in the cleaning and activation of metal surfaces, especially before electroplating.
5. Cosmetic Industry: Used in hair bleaching formulations and as a component in hair coloring products.
6. Wastewater Treatment: Assists in the removal of contaminants through oxidation processes.

Handling and Storage:

• Handling:
  • Avoid contact with skin, eyes, and clothing.
  • Use personal protective equipment (PPE) such as gloves, goggles, and protective clothing.
  • Ensure good ventilation at the workplace to avoid inhalation of dust.
  • Avoid mixing with combustible materials, acids, and organic substances, as this could lead to a violent reaction.
  • Handle with care to prevent dust formation, which can be explosive under certain conditions.
• Storage:
  • Store in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials.
  • Keep the container tightly closed to prevent moisture absorption and contamination.
  • Store separately from reducing agents, acids, and organic materials.
  • Ensure proper labeling and keep the product in original packaging.

Safety Considerations:

• Hazard Statements: APS is an oxidizer and can intensify fires. It may cause respiratory irritation, skin, and eye irritation.
• 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.
