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.

Application

1. As a source of radicals, APS is mainly used as a radical initiator in the polymerization of certain alkenes. Commercially important polymers prepared using persulfates include styrene-butadiene rubber and polytetrafluoroethylene.

 

1. Illustrative of its powerful oxidizing properties, ammonium persulfate is used to etch copper on printed circuit boards as an alternative to ferric chloride solution.This property was discovered many years ago.

 

1. Ammonium persulfate is a standard ingredient in hair bleach.

 

1. Persulfates are used as oxidants in organic chemistry.For example, in the Minisci reaction and Elbs persulfate oxidation

Storage
Precautions for storage: Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat source. The package must be sealed to prevent moisture. Should be stored separately from the reducing agent, active metal powder, etc., do not mix storage. The storage area shall be provided with suitable materials to contain spills.
