Bisulphate is a white crystalline powder. It has a fast decomposition rate in humid air and high temperature. It is decomposed by ethanol and silver ions. The solubility of water at 20℃ is 549g/L; sodium persulfate is in humid air and high temperature. , Will accelerate the decomposition of sodium persulfate and turn it into sodium pyrosulfate.
The bis-sodium sulfate solution is acidic and can be decomposed by alcohol and silver ions. It can also burn with combustibles or easy oxides to support combustion, promote fire, and even explode when it is violent. The high sodium sulfate solution decomposes very slowly during storage, and decomposes obviously at room temperature, which is a strong oxidation reaction.
So what is the use of sodium persulfate?
Used in sodium persulfate, oxidizer, emulsion polymerization accelerator, etc. It can also be used in the treatment of waste liquids in the photographic industry, metal corrosives on the surface of printed circuit boards, textile desizing agents, sulphur dyes and coloring agents. Used in oil well fracturing fluid gel breaker, battery depolarizer, organic polymer emulsion polymerization initiator. The photosensitive industry is mainly used in film development, fixers, waste liquid treatment agents, metal surface treatment agents, and etching agents for printed circuit boards.
If used improperly, the amount of sodium persulfate will be greatly reduced. Therefore, sodium persulfate should be stored in a dry, cool and well-ventilated warehouse. Keep heat sources away from ignition. At 30°C, the relative humidity cannot exceed 80%. After use, it should be sealed and stored separately from reducing agent, active metal powder, alkali, alcohol, etc., and do not mix.
