Sodium Persulfate, is a white crystal or crystalline powder, odorless, tasteless.Gradual decomposition at room temperature, heating or rapidly decompose in ethanol, decomposition to release oxygen and produce sodium pyrosulfate. Moisture and platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can promote the decomposition, it decomposes rapidly and emit hydrogen peroxide at high temperature (about 200 ℃). It is soluble in water (70.4 when 20 ℃).

Stability Unstable. Strong oxidizer. Contact with combustible material may cause fire. Incompatible with combustible material, strong reducing agents, strong bases, alcohols, aluminium, magnesium. Protect from moisture.
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,easy and safe to handle,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.
1,Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl
acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene
2,Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;cleaning
and etching of printed circuits),activation of copper and aluminium surfaces.
3,Cosmetics : Essential component of bleaching formulations.
4,Paper : modification of starch,repulping of wet - strength paper.
5,Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)
