Here is a general knowledge of potassium persulfate:

Potassium persulphate is widely used in industrial production and consumption because of its strong and effective non-chlorine oxidation capacity and the safety and environmental protection requirements in the use and treatment process. Generally, it is relatively stable under the state, and decomposition reaction is easy to occur when the temperature is higher than 65℃. Relatively active, easy to participate in a variety of chemical reactions, can be used as an oxidant, bleach, catalyst, disinfectant, etching agent, etc.
