Ammonium persulfate is widely used as an oxidizing agent in various industrial and chemical processes. It is commonly employed in the polymerization of acrylic monomers, where it acts as an initiator to start the reaction and form polymers. In the electronics industry, it is utilized for etching printed circuit boards, helping to remove copper and create precise circuit patterns. Additionally, it serves as a cleaning agent for metal surfaces, effectively removing oxides and contaminants. In hair bleaching and cosmetic formulations, it is used to decolorize hair by breaking down melanin. It also finds application in water treatment processes, where it aids in the oxidation of organic pollutants and improves water quality.
