Sodium Persulfate is a white odorless crystal or powder, which is decomposed by ethanol and has good stability at room temperature. It is often used as an oxidizing agent, and can also be used as a monomer polymerization initiator. It hardly absorbs moisture, is easy to store, convenient and safe to use.

Description
Sodium Persulfate is a white,crystalline,odourless salt.It is used as initiator for the Polymerization of monomers and as a strong oxidizing agent in many applications.It has the particular advantage of being almost non - hygroscopic,of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.
Sodium Persulfate has strong oxidizing. There is a strong irritation to the skin, prolonged contacting with the skin can cause allergies, should pay attention to it when operation. It should be Sealed storage. heat the ammonium persulfate and sodium hydroxide or sodium carbonate solution to remove carbon dioxide and ammonia to obtain sodium persulfate in the laboratory.

Application
Environmental remediation agents: contaminated soil remediation, water treatment (wastewater purification); Waste gas treatment, oxidative degradation of harmful substances (e.g. mercury).
Polymerization: initiator of latex or acrylic monomer polymerization liquid, vinyl acetate, vinyl chloride and other products, and initiator of copolymerization of styrene, acrylonitrile, butadiene and other colloid.
Metal treatment: cleaning and pickling of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.
Used to accelerate the processing of low concentration formalin adhesive.
A regulator for the production of starch and used as a desizing agent in the production of adhesives and coatings.
Cosmetics: the main ingredient of bleaching formula.
Textiles: desizing and bleaching agents - especially for low temperature bleaching.
Hair dye: it is one of the basic components of hair dye and plays a decolorizing role.
Others: chemical synthesis; Disinfectant.
