过硫酸铵

ammonium persulfate is a white, crystalline, odourless salt. It is used as initiator for the polymerization of monomers and as a strong oxidizing agent in many application. It has the particular advantage of being almost nonhygroscopic, of having a particularly good storage of stability as a result of its extremely high purity and of being easy and safe to handle.
