Storage

APS is not combustible but assists combustion materials due to release of oxygen. It must be stored dryly in closed containers and protected from direct sunlight, heat and humidity. Impurities such as dirt, rust or traces of metal and reductants may cause catalytic decomposition. The product as supplied or in solution needs to be handled with appropriate care. The eye, skin and clothes must be protected when working with APS. APS as damp powder or aqueous solution has a bleaching and slightly corroding effect. Recommended storage temperature: normal temperature. Storage stability as from date of delivery: 12 months.

Application

Widely used in storage battery industry.  Used to produce persulfates and refine of Ammonia Sulfate.
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 etc..
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.
Used in decoloring and bleaching of oil, cleaning and deodorization of deteriorated barm, as ripener of wheat.
Used as additive of under-well fracturing in petroleum exploitation.
Used in developer and fixer of film, widely used in the treatment of waste fluid.
Cosmetics: Essential component of bleaching formulations. Textile: Desizing agent and bleach activator - particularly for cold bleaching.
Chemical synthesis; Water treatment (decontamination); Waste gas treatment, oxidative degradation of harmful substances (e.g. Hg); Disinfectant; Paper (modification of starch, repulping particularly for cold bleaching).
