Sodium persulfate is a white tasteless crystal or powder, also known as high sodium sulfate. Sodium sulfate is stable at room temperature and decomposes gradually at high temperature. At 20 ℃, it is dissolved in 549g / L water with ethanol and silver ion as solvent. Its relative density is 2.400 (superposition density: 0.7), which can accelerate the oxidation reaction. Small absorption rate, convenient storage and safe use.

Sodium persulfate method was formed by the reaction of ammonia sulfate and sodium hydroxide in aqueous solution. Ammonium persulfate crystal is obtained from the original solution of ammonium persulfate by vacuum crystallization and centrifugal filtration, then sodium persulfate solution is obtained by vacuum crystallization and centrifugal filtration, then sodium persulfate solution is obtained by vacuum crystallization and centrifugal filtration, and then sodium persulfate crystal is obtained by vacuum crystallization and centrifugal filtration.

Sodium persulfate can be used as initiator in emulsion or acrylic monomer polymerization solution, as initiator in vinyl acetate and vinyl chloride, and as metal surface treatment agent; Sodium persulfate can be used as the main component of bleaching formula; Sodium persulfate can also be used as waste gas treatment, oxidation and degradation of harmful substances, disinfectant, etc.
