Propriétés chimiques
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.

Applicationn

  1. En tant que source de radicals, APS is mainly used as a radical initiatordans le polymerization de certains alkenes. Commercially important polymers prepared using persulfates include styrene-butadiene rubberetpolytetrafluoroethylene.
  2. Illustrative of its powerful oxidizing properties, ammonium persulfate is used to etch coppersur printed circuit boards comme alternative à ferric chlorideThis property was discovered many years ago.
  3. Le persulfate d'ammonium est un ingrédient standard dans hair bleach.
  4. Les persulfates sont utilisés comme oxidantsdans organic chemistry.For example, in the Minisci reactionetElbs persulfate oxidation
