Main Applications:

1. Polymerization Reactions as an Initiator:
   • Sodium persulfate is commonly used as a free radical initiator in polymerization reactions. It is widely applied in emulsion polymerization, solution polymerization, and suspension polymerization. It generates free radicals, which initiate polymerization reactions, particularly in the synthesis of polyethylene, polypropylene, and polystyrene.
2. Cleaning Agents and Water Treatment:
   • In wastewater treatment, sodium persulfate is often used to oxidize organic pollutants and remove harmful substances from water, such as aromatic compounds and toxic gases.
   • It is also used in metal cleaning to remove oxides and contaminants from metal surfaces.
3. Chemical Synthesis:
   • As an oxidizing agent, sodium persulfate is used in organic synthesis reactions, such as the oxidation of alcohols and phenols.
   • It is also employed in the production of fine chemicals and pharmaceuticals, acting as a strong oxidizer in specific reactions.
4. Textile and Dyeing Industry:
   • In the textile industry, sodium persulfate is used for bleaching fabrics, removing stains, and ensuring uniformity in the dyeing process.
5. Electronics Industry:
   • In the electronics industry, sodium persulfate is used for cleaning and etching circuit boards, removing oxide layers and contaminants to ensure the performance of the boards.
