Sodium persulfate is an acidic substance. Sodium persulfate, also known as sodium persulfate. White crystals or crystalline powders. No smell. Odorless. Molecular formula Na2S2O8, relative molecular weight 238.13. It gradually decomposes at room temperature, and can be rapidly decomposed by heating or in ethanol. After decomposition, oxygen is released and sodium pyrosulfate is generated. Moisture and metal ions such as platinum black, silver, lead, iron, copper, magnesium, nickel, manganese, or their alloys can promote decomposition. At high temperatures (around 200 ℃), rapid decomposition occurs, releasing hydrogen peroxide. Easy to dissolve in water (70.4 at 20 ℃).

Has strong oxidizing properties. Strong irritant to the skin, prolonged contact with the skin can cause allergies, and attention should be paid during operation. Rat oral LD50 895mg/kg. Sealed storage. The laboratory obtains sodium persulfate by heating a solution of ammonium persulfate with caustic soda or sodium carbonate to remove ammonia and carbon dioxide.

Precautions for operating sodium persulfate:

Sealed operation, strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear a hood type electric air supply filter dust respirator, polyethylene gas protective clothing, and rubber gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Avoid generating dust. Avoid contact with reducing agents, active metal powders, alkalis, and alcohols. Handle with care during transportation to prevent damage to packaging and containers. Vibration, impact, and friction are prohibited. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.
