The sterilization characteristics of potassium persulfate are as follows: 


1. The active oxygen concentration of potassium persulfate can reach 8-10%. It can effectively kill bacteria after only 10-20 minutes of contact with water, and it can kill bacteria for up to 72 hours. 


2. The active oxygen continuously generated by the water through the cyclic reaction activates small molecule high-energy powders, which through chain reactions produce various high-energy and highly active free radicals, such as new ecological oxygen free radicals, hypochlorous acid, hydroxyl free radicals, hydrogen peroxide, sulfate free radicals, and other active components, maintaining the sterilization ability. 


3. Multiple active ingredients coexist, capable of killing viruses, fungi, spore-forming bacteria, etc. 


4. The potassium peroxydisulfate produced by our company is less affected by water quality. 


5. Non-toxic, without harmful carcinogens, no teratogenic or mutagenic by-products. 


A detailed explanation of the sterilization principle of potassium peroxydisulfate 


From a molecular structure perspective, potassium persulfate is extremely similar to peracetic acid. The peroxide bonds in potassium persulfate are connected to sulfur atoms and carbon atoms. Potassium persulfate is an inorganic substance, and its disinfection active component is the monosulfuric acid radical ion. It can oxidize the proteins of microorganisms, causing the microorganisms to die. Monosulfuric acid potassium is a neutral salt. The acidity of its aqueous solution is caused by the dissolution of potassium bisulfate in the compound salt, which generates hydrogen ions. However, potassium persulfate has much better stability in acidic conditions than in neutral conditions, and it will rapidly decompose in alkaline conditions. The potassium persulfate compound salt obtained through compounding is a disinfectant made of sodium chloride, organic acids, and monosulfuric acid potassium. In aqueous solution, it utilizes the special oxidation ability of monosulfuric acid potassium to undergo a chain reaction, continuously generating new oxygen radicals, hypochlorous acid, free hydroxyl groups, and hydrogen peroxide. Through the oxidation effects of new oxygen radicals and free hydroxyl groups, the permeability of the cell membrane can be changed, causing it to rupture, thereby protecting the normal protective layer and achieving the purpose of killing bacteria, fungi, protozoa, and viruses. 


Furthermore, the new eco-oxygen, hypochlorous acid, and free hydroxyl groups can all simultaneously kill microorganisms. Therefore, after dissolution, they achieve the maximum synergistic sterilization effect. Hence, the sterilization performance of potassium peroxydisulfate compound salt is much better than that of other disinfectants. At the same time, the chloride released after killing microorganisms will be oxidized by the active oxygen of potassium peroxydisulfate into hypochlorous acid and free hydroxyl groups, which will persist in action. Thus, the potassium peroxydisulfate compound salt has the characteristics of high efficiency, broad-spectrum, rapid action, long-lasting effect, and safety in the disinfection function.
