Chemical generalists: The magical uses of ammonium persulfate（AP/APS）

In the bright star of chemical industry, ammonium persulfate has become a shining star with its unique chemical properties and wide application fields. This white crystal, with the chemical formula (NH4)2S2O8, plays a vital role in several industrial fields due to its multi-faceted nature and high efficiency.

1.Bleach for the paper industry

Ammonium persulfate acts as a bleach agent in the paper industry. It removes lignin and pigment through oxidation reaction, significantly improving the whiteness and brightness of paper. This process not only improves the appearance quality of the paper, but also enhances the physical properties of the paper, such as strength and water resistance.

2.Pretreatment agent for textile industry

3.In the textile industry, ammonium persulfate is used as a pre-treatment agent to effectively remove impurities such as waxes, pectin and pigments from cotton and other natural fibers. This step is essential to improve the dyeing uniformity and color fastness of the fabric, ensuring the quality of the final product.

3.Cleaning agentsfor the electronics industry

In the electronics industry, the cleaning capabilities of ammonium persulfate are critical to the manufacture of circuit boards and other electronic components. It can remove oxides and residues on metal surfaces to ensure the purity and performance of electronic components, thereby improving the reliability and life of electronic products.

4. Polymerization initiatorfor plastics industry

In the plastics industry, ammonium persulfate is used as a polymerization initiator to promote the polymerization reaction of plastics and improve the properties of plastics. It is able to improve the mechanical strength and heat resistance of plastics, making them more suitable for a variety of applications, such as packaging materials, automotive components and building materials.

5.Synthetic catalystsfor the pharmaceutical industry

In the field of medicine, the oxidation of ammonium persulfate(APS) makes it a key catalyst for the synthesis of some drugs. It is involved in the synthesis of many drugs, including antibiotics, anti-inflammatory drugs and cardiovascular drugs, contributing to the cause of human health.

6.Water treatment agent for environmental protection

Ammonium persulfate also plays an important role in the field of environmental protection, especially in water treatment. It can decompose organic pollutants in water, such as dyes, pesticides and toxic substances in industrial wastewater, thereby purifying water quality and protecting the environment.
