Ammonium persulfate is a white monomeric crystal with the density of 1.98.It can be wholly decomposed under 120°C,and reserve nondecomposabl for a long period under entire desiccation.It is almost non – hygroscopic,and will gradually decomposed to emit oxygen and ozone after hygroscopic effect.It will be decomposed while being dissolved in the water and being heated.It is used as chemical reagent,oxidant,bleacher,deodorizer,and initiator for the polymerization of monomers.It has the particular advantage of having strong oxidation and of being easy and safe to handle.
