Ammonium persulfate is a white monomeric crystal with the density of 1.98.It can be wholly decomposed at 120 ℃. It can be reserved non-decomposable for long period when completely dried. It has low hygroscopy and will gradually decompose to emit oxygen and ozone after absorbing moisture. It decomposes 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. It’s easy and safe to handle.
