Sodium Persulfate

Sodium persulfate (SPS), a stable salt of peroxodisulfuric acid, is a strong yet easy-to-dose oxidant and an excellent radical source in aqueous media. RheinPerChemie serves the product in the form of colour- and odourless crystalline powders. Due to its high purity and low moisture content, SPS from RheinPerChemie is storage-stable and can be handled safely. Occasionally, SPS tends to form lumps or cake when stored under ambient conditions. Small amounts of special silica additives can suppress this behaviour. Sodium persulfate is highly water-soluble. Aqueous solutions react slightly acidic and are less storage-stable than anhydrous solids.

Due to its high oxidation potential, SPS can decompose when subjected to adverse conditions. The product itself is not flammable but oxidising.
