Usage of potassium persulfate 1 Disinfection of the surface of public environment objects: disinfection can be carried out by spraying and wiping. Concentration 100 mg/L ~ 300 mg/L for 20min. 2. Air disinfection in public places: 3000mg/L concentration, 5ml/m3 spray for 30min. 3. Disinfection of hospital wards and outpatient clinics: articles that are not afraid of corrosion and medical instruments with certain corrosion resistance can be disinfected with potassium persulfate disinfectant, such as thermometers, tongue depressors and endoscopes. , the concentration is 2000 mg/L, and the action lasts for 30 minutes. The equipment with obvious pollution can be cleaned first and disinfected with 5000mg/L potassium persulfate and trace surfactant for 20min minutes. The hospital sewage is dosed quantitatively with special dosing equipment according to the ratio of 10g/t ~ 15g/t for 60 minutes. 4. Disinfection of tableware: For tableware and tea sets, 200 mg/L ~ 1000 mg/L potassium persulfate disinfectant can be used to clean, soak and disinfect for 5 min ~ 10 min. It can also be used with detergents such as detergent to disinfect tableware, and then rinse with clean water after disinfection. 5. Advanced treatment and disinfection of drinking water: it can be used for disinfection of tap water and advanced treatment of drinking water. Generally, the dosage is 0.5 mg/L ~ 3 mg/L for 5 min ~10 min.

Potassium persulfate refers to the double salt of potassium persulfate, which is an inorganic acid oxidizer. Potassium persulfate double salt is a new active oxygen disinfectant. As the fifth generation disinfectant, it has a very strong and effective chlorine-free oxidation ability. Its aqueous solution is acidic, which is very suitable for disinfection of various water bodies. After dissolution, high-activity small molecular free radicals, active oxygen and other derivatives are generated, and toxic by-products will not be formed in water, which is extremely safe. Potassium persulfate can be used in different time periods, when the water transparency is high, it can be used in the sun, and when the transparency is low, it can be used at night. After use, algae can sink, remove algal toxins, decompose organic matter and increase dissolved oxygen. Aquatic animals are prone to various problems at night, and a good bottom environment can enhance the vitality of aquatic animals.

Potassium monopersulfate is very similar to peracetic acid, and the peroxy bond is connected to sulfur atom and carbon atom respectively. Potassium persulfate is an inorganic substance, and its effective disinfectant component is hydrogen persulfate ion, which can oxidize the protein of microorganisms and lead to their death. Potassium monopersulfate is a neutral salt, and the acidity of its aqueous solution is caused by the dissolution of potassium monopersulfate in double salt to produce hydrogen ions. However, the stability of potassium persulfate under acidic conditions is far better than that under neutral conditions, and it will decompose rapidly under alkaline conditions. The compound potassium persulfate double salt is a potassium persulfate double salt disinfectant made of sodium chloride, organic acid and potassium persulfate. In aqueous solution, using the special oxidation ability of potassium monopersulfate, a chain reaction occurs in water, and new ecological oxygen, hypochlorous acid, free hydroxyl and hydrogen peroxide are continuously generated. Through the oxidation of new ecological oxygen and free hydroxyl, the permeability of cell membrane is changed and destroyed, so that the protective layer is normal and the purpose of killing bacteria, fungi, protozoa and viruses is achieved.
