Products » Persulphate
The term persulphate refers to ions or compounds with more oxygen than normal sulfates.
These do not have sulfur in a different oxidation state; rather, they contain peroxide units, where two oxygens take the place of one in a normal sulfate; the oxygen atoms are in oxidation state −1.
The main forms are peroxomonosulfates and peroxodisulfates.
Ammonium Persulphate
Ammonium persulphate (NH4)2S2O8 has been prepared by H. Marshall[1] by the method used for the preparation of Potassium persulfate. It is very soluble in cold water, a large fall of temperature accompanying solution. It is a very strong oxidizing agent and a radical initiator. It is used to etch copper on printed circuit boards as an alternative to ferric chloride solution[citation needed] It is also used along with tetramethylethylenediamine to catalyze the polymerization of acrylamide in making a polyacrylamide gel.
Potassium persulphate
Potassium persulphate (K2S2O8) is a chemical compound. It is a food additive and it is used in organic chemistry as an oxidizing agent for instance in the Elbs persulfate oxidation
Conditions/substances to avoid are: heat, flames, ignition sources, powdered metals, phosphorus, hydrides, organic matter, halogens, acids and alkalis.
Sodium Persulphate
Sodium persulfate (Na2S2O8) is a chemical compound. It is a strong oxidizer. It is a severe irritant of skin, eyes, and respiratory system. It is almost non-hygroscopic and has particularly good ability to be stored for long time. It is easy and safe to handle. It is not combustible, but releases oxygen easily and assists combustion of other materials.
