    • Potassium persulfate is often used as a initiator for polymerization reactions, particularly in the production of acrylics, styrene-based polymers, and other synthetic resins. It initiates the formation of polymer chains by breaking double bonds and creating free radicals that facilitate the polymerization process.

    • Treatment of metal surfaces (eg in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.

      In the electronics industry, potassium persulfate is used as an etching agent for printed circuit boards (PCBs). It is used to remove the unwanted copper from the board's surface during the manufacturing process.

    • Potassium persulfate is used in water treatment to remove organic pollutants, such as chlorine byproducts and pesticides. It is also used to disinfect water.

    • In environmental applications, potassium persulfate is used for in situ chemical oxidation (ISCO) to remediate contaminated soil and groundwater. It helps in breaking down organic contaminants in the subsurface.

    • In the beauty industry, potassium persulfate is used as an oxidizing agent in hair perm formulations. It helps to break and reform disulfide bonds in hair, allowing for the desired curling or straightening effects.

    • In textile processing, potassium persulfate is used to remove the sizing agents from fabrics. Sizing agents are applied to fabrics to improve their weaving and handling characteristics, and potassium persulfate helps in their removal.
