Ammonium Persulfate (APS) is a white, crystalline, odorless salt commonly used as an oxidizing agent in a wide range of industrial applications. It is also used as a bleaching agent in hair dyes, as a polymerization initiator in the manufacture of plastics, and as an etchant in printed circuit board manufacturing.
In this article, we will provide a comprehensive guide on Ammonium Persulfate, including its properties, uses, benefits, hazards, and how it works.
Ammonium Persulfate is a chemical compound with the formula (NH4)2S2O8. It is composed of two ammonium ions (NH4+) and two persulfate ions (S2O82-). It is a strong oxidizing agent with a molecular weight of 228.20 g/mol.
Ammonium Persulfate is a white, crystalline salt that is soluble in water. It has a density of 1.98 g/cm³ and a melting point of 120°C. It is odorless and has a pH of approximately 1.5.
Ammonium Persulfate is widely used as an oxidizing agent in a range of industrial applications, including:
Manufacturing of dyes and pigments
Bleaching of textiles
Treatment of wastewater
Extraction of metals from ores
Electropolishing of metals
Chemical polishing of metals
Production of adhesives and sealants
Production of paper and pulp
Ammonium Persulfate is also used as a bleaching agent in hair dyes. It is a common ingredient in hair bleach powders and hair color removers.
Ammonium Persulfate is used as a polymerization initiator in the manufacture of plastics. It is a key component in the production of acrylics, polyvinyl chloride (PVC), and other types of plastic.
Ammonium Persulfate is used as an etchant in the manufacturing of printed circuit boards (PCBs). It is used to remove copper from the surface of the PCB to create circuit pathways.
Ammonium Persulfate offers several benefits in industrial and commercial applications, including:
It is a powerful oxidizing agent that can be used to remove impurities from materials
It is effective in bleaching hair and removing hair dye
It is a key component in the manufacture of plastics and PCBs
It is relatively inexpensive and readily available
Ammonium Persulfate poses several hazards to human health and the environment.
Ammonium Persulfate can cause irritation to the skin, eyes, and respiratory system. Prolonged or repeated exposure to Ammonium Persulfate can cause allergic reactions, including asthma and dermatitis.
Ammonium Persulfate can have harmful effects on the environment, particularly on aquatic organisms. It can deplete oxygen levels in water, which can lead to the death of fish and other aquatic life.
Ammonium Persulfate works as an oxidizing agent by breaking down into sulfate and ammonium ions when dissolved in water. It reacts with organic compounds, such as dyes, pigments, and polymers, to remove impurities and produce desired chemical reactions.
In hair dyeing and bleaching, Ammonium Persulfate reacts with the melanin in hair to break down its structure and remove the color. In the production of plastics and PCBs, it initiates the polymerization process by reacting with monomers to form long chains of polymers.
Qi Di Chem (Aozun Chemical) was established in 2003, is specialized in manufacturing persulfate series products (Ammonium Persulfate, Sodium Persulfate, Potassium Persulfate).
