Used as a strong oxidizing agent in organic synthesis, particularly in emulsion polymerization to initiate radical reactions. Commonly applied in the production of polymers like polystyrene and synthetic rubbers. Also utilized in environmental testing to digest organic matter in water samples, enabling determination of total phosphorus and nitrogen content. In electronics, employed for micro-etching copper surfaces to improve adhesion in printed circuit board manufacturing. Effective in wastewater treatment for breaking down refractory pollutants through advanced oxidation processes.
