dvr Ammonium Persulfate (Pwd)

Ammonium Persulfate manufacturers, suppliers and exporters. Well known Bleaching agent for food starch Ammonium persulfate (NH4)2S2O8 is a strong oxidizing agent. It is very soluble in cold water, a large fall of temperature accompanying solution. It is a radical initiator. It is used to etch copper on printed circuit boards as an alternative to ferric chloride solution. It is also used along with tetramethylethylenediamine to catalyze the polymerization of acrylamide in making a polyacrylamide gel.

Remarks:


Storage : Ammonium Persulfate is hygroscopic and must be stored under dry conditions. It has to be protected from direct sunlight and from any other source of heat.

Ammonium Persulfate is a white, crystalline, odourless salt consisting of technically pure ammonium peroxydisulfate with selected particle size distribution and silicic acid to enhance the free-flowing properties.  Ammonium Persulfate has also been utilized to study protein-protein interactions via photoinitiated crosslinking chemistry. Other applications of Ammonium Persulfate include its use as a reducer and retarder in photography, the manufacture of aniline dyes, electroplating, the decolorizing and deodorizing of oils. A protocol on the APS-mediated modification of polypropylene membranes with polyaniline has been published. Ammonium Persulfate has been used to prepare biodegradable macroporous hydrogels for application as cross-linkable biomaterials. 

Using Procedure:

The most important application for Ammonium Persulfate is in the water-based emulsion polymerisation of organic monomers in aqueous systems. The monomers are either sufficiently soluble in water and precipitate during polymerisation or polymerisation takes place in an aqueous emulsion of the monomers, as with styrene-butadiene and Acrylonitrile.

Other applications of Ammonium Persulphate (APS)

  • In the cosmetics industry as a booster for hair bleaches and an oxidizer in hair dyes
  • In the paper industry for re-pulping and de-inking
  • In order to recover metals and metal salts, for oxidative treatment of high grade metal ores
  • In the photographic industry for regenerating bleaching baths for color stock
  • For the production of desinfectants
  • In-situ decontamination of industrial areas: degradation of chlorinated hydrocarbons
  • In Oil Drilling
