Uses of potassium persulfate:

• Chemical production: Potassium persulfate is used in the production of various inorganic chemicals, including ammonium persulfate, sodium persulfate, and hydrogen peroxide.
• Textile bleaching: Potassium persulfate is a powerful bleaching agent used in the textile industry to remove color from fabrics. It is particularly effective in bleaching cotton and wool.
• Polymerization initiator: Potassium persulfate is used as a polymerization initiator in the production of various polymers, including acrylics, polyvinyl chloride (PVC), and polyethylene.
• Etching: Potassium persulfate is used as an etching agent in the production of printed circuit boards and other electronic components.
• Water treatment: Potassium persulfate is used in water treatment processes to remove organic contaminants and improve water quality.

Safety of potassium persulfate:

Potassium persulfate is a strong oxidizing agent and should be handled with care. It can cause irritation to the skin, eyes, and respiratory system.

It is important to wear appropriate personal protective equipment, including gloves, goggles, and a respirator, when handling potassium persulfate.

Potassium persulfate should be stored in a cool, dry place away from heat and sources of ignition.

• In case of contact with skin or eyes, flush the affected area with water immediately for at least 15 minutes. Seek medical attention if necessary.
• In case of inhalation, move the person to fresh air and seek medical attention if necessary.

Potassium persulfate should be disposed of as hazardous waste in accordance with local regulations.
