Use
Sodium persulfate, also known as sodium peroxydisulfate is White crystal or crystalline powder, odorless, tasteless. Formula is Na2S2O8, relative molecular mass is 238.13. Gradual decomposition at room temperature, heating or rapidly decompose in ethanol, decomposition to release oxygen and produce sodium pyrosulfate. Moisture and platinum black, silver, lead, iron, copper, magnesium, nickel, manganese and other metal ions or their alloys can promote the decomposition, it decomposes rapidly and emit hydrogen peroxide at high temperature (about 200 ℃). It is soluble in water (70.4 when 20 ℃). It has strong oxidizing. There is a strong irritation to the skin, prolonged contacting with the skin can cause allergies, should pay attention to it when operation. Rat oral LD50 is 895mg/kg. It should be Sealed storage. heat the ammonium persulfate and sodium hydroxide or sodium carbonate solution to remove carbon dioxide and ammonia to obtain sodium persulfate in the Laboratory.
