Ammonium persulfate, abbreviated as APS, CAS number 7727-54-0, is a white crystalline powder that is easily soluble in water and has strong oxidizing and corrosive properties. It is relatively stable at room temperature, but it is prone to decomposition and release oxygen when heated. This characteristic makes it an important chemical reagent and raw material in many fields such as chemical engineering, electronics, and textiles, and has a wide range of applications. ​

Ammonium persulfate is a commonly used free radical initiator in polymerization reactions, playing a crucial role in the polymerization or copolymerization of monomers such as acrylic esters and styrene. For example, in the preparation of water-soluble polymers such as polyacrylamide and polyacrylic acid, APS can decompose to produce free radicals, triggering monomer polymerization reactions and controlling the reaction rate and molecular weight of the polymer. In lotion polymerization, it can form an oxidation-reduction initiator system with sodium bisulfite to reduce the activation energy of the reaction, so that the polymerization can proceed smoothly at a lower temperature, and it is widely used in coatings, adhesives, synthetic rubber and other industries.

In the electronics industry, ammonium persulfate is commonly used as an etchant for printed circuit boards (PCBs). It can react chemically with copper to dissolve and remove unwanted copper layers on the circuit board, forming fine circuit patterns. This etching process has the characteristics of fast speed and high precision, which can meet the production needs of miniaturization and high-density electronic components. In addition, APS can be used for etching and roughening of metals in metal surface treatment, enhancing the adhesion between metal surfaces and coatings, and improving product quality. ​

Ammonium persulfate has strong oxidizing properties and has important applications in the field of bleaching. In the textile industry, it can be used as a bleaching agent for fabrics, especially for protein fibers such as wool and silk. It can effectively remove pigments and impurities from fabrics, making them white in color and causing minimal damage to fibers. In the paper industry, APS can be used for bleaching pulp, improving the whiteness of pulp and enhancing the appearance quality of paper. In addition, it can also be used as an oxidant for wastewater treatment, removing reducing pollutants from water and purifying water quality. ​

In the field of chemical engineering, ammonium persulfate can be used as an oxidant to participate in various chemical reactions, such as the synthesis of organic peroxides and dye intermediates. In analytical chemistry, it can be used as a chemical reagent for quantitative analysis, such as determining the content of metal ions such as manganese and chromium, and achieving precise detection through redox reactions. At the same time, APS can also be used for soil analysis to help determine the organic matter content in soil and provide data support for agricultural production. ​

In the cosmetics industry, ammonium persulfate can be used for the preparation of hair bleaching agents, which can decompose melanin and achieve the effect of lightening hair. In the field of medicine, it can be used as an oxidant in the synthesis process of certain drugs, assisting in the generation of specific chemical structures. In the laboratory, APS is a commonly used chemical reagent, commonly used in polymer material synthesis experiments, water quality testing experiments, etc., providing convenience for scientific research work. In addition, it can also be used as a vulcanization accelerator in the rubber industry, accelerating the vulcanization speed of rubber and improving its performance. ​
