Chemical Properties
Peroxodisulfate contains peroxy groups and is a strong oxidant that can oxidize Mn2 + to MnO4-. Ammonium peroxodisulfate can be prepared by electrolysis of an aqueous solution of ammonium bisulfate.
Ammonium persulfate soluble in water
.
1)Widely used in storage battery industry. Used to produce persulfates and refine of Ammonia Sulfate.
2)Used as additive of under-well fracturing in petroleum exploitation.
3)Used in developer and fixer of film, widely used in the treatment of waste fluid.
4)Cosmetics: Essential component of bleaching formulations.
5)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..
6)Textile: Desizing agent and bleach activator - particularly for cold bleaching.
7)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.
8)Used in decoloring and bleaching of oil, cleaning and deodorization of deteriorated barm, as ripener of wheat.
9)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).
