Ammonium persulfate is widely used as an oxidizing agent in various industrial and chemical processes. In the polymer industry, it serves as a key initiator for the polymerization of monomers like acrylonitrile, styrene, and vinyl chloride, facilitating the production of plastics, resins, and synthetic rubbers. It is also employed in the etching of printed circuit boards (PCBs) in electronics manufacturing, where it helps remove copper layers to create precise circuit patterns. Additionally, ammonium persulfate is utilized in hair bleaching formulations due to its ability to break down melanin pigments. In environmental applications, it is used for soil and groundwater remediation to oxidize and degrade organic contaminants. Its strong oxidizing properties also make it suitable for cleaning and disinfecting surfaces in industrial settings.
