Oxidation potential: 2.01 V
Reduction potential: -0.70 V
Potassium Persulfate finds a wide range of applications across various industries. Some of the most prominent applications include:
Potassium Persulfate is used in the textile industry as a bleaching agent for wool, silk, and other textiles. It is also used to remove residual dyes and to bleach cotton and other natural fibers.
Potassium Persulfate is used as an etchant for printed circuit boards in the electronics industry. It is used to remove copper from the board, leaving behind the desired circuit pattern.
Potassium Persulfate is a popular initiator for the polymerization of acrylic monomers. It is also used in emulsion polymerization reactions and as a crosslinking agent in the production of rubber.
Potassium Persulfate is also used in the pharmaceutical industry for the synthesis of various compounds. It is also used in the water treatment industry to remove metal ions from wastewater.
Potassium Persulfate is a highly reactive and potentially hazardous compound. Some of the safety measures that must be taken when working with potassium persulfate include:
Wear appropriate personal protective equipment, including gloves and goggles.
Store Potassium Persulfate in a cool, dry, and well-ventilated area.
Avoid inhaling or ingesting Potassium Persulfate.
Do not mix Potassium Persulfate with other chemicals without proper precautions.
Follow all handling and storage instructions provided by the manufacturer.
