Storage and notes
Chronic Persulfate is non-flammable, but since it can release oxygen and has combustion promoter effect, it must be stored under certain conditions. Firstly, it must be stored in a dry and airtight container. Secondly, it should avoid direct sunlight, heat source, humidity and other adverse factors. In addition, some impurities such as dirt, rust, a small amount of metal and reducing agent may cause decomposition of this, which deserves our attention in the process of storage and use. Since the humidity level of sulfate powder and its aqueous solution have bleaching and mild corrosion effects, the skin, eyes and clothes should be avoided to contact directly with them during application.
