★ The red box shows the test results of our sample, with impurities far below the average level of our peers.

Our sodium persulfate has been able to reach the leading level compared with the same industry through trace element test, and the trace elements are controlled at a very low level. Our production process for sodium persulfate uses pure water.

This specification of sodium persulfate can be used in circuit boards, PCB, fine chemicals and other industries.



Description

SODIUM PERSULFATE DESCRIPTION


Sodium Persulfate (SPS) 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.


Sodium Persulfate (SPS) 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 (SPS) 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. Sodium Persulfate 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.


Chemical Properties

Sodium Persulfate is a white, crystalline powder. Soluble in water; decomposed by alcohol; decomposes in moist air. Very irritating to skin and eyes. May be toxic by skin absorption


Storage Characteristics

Sodium Persulfate is a strong oxidizer and a severe irritant of skin, eyes, and respiratory system. It is almost non-hygroscopic and has particularly good ability to be stored for long time. It is easy and safe to handle. It is not combustible, but releases oxygen easily and assists combustion of other materials.
Conditions/ substances to avoid mixing persulfates with are: moisture, heat, flame, ignition sources, shock, friction, reducing agents, organic material, sodium peroxide, aluminum and powdered metals.



Application

SODIUM PERSULFATE 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.
