Potassium persulfate is widely used indisinfectants and bleach because of its strong oxidizing properties. The following are the specific applications of potassium persulfate in these
fields:
1. Disinfectant: Potassium persulfate canbe used for the preparation of disinfectants, and its strong oxidation performance can effectively kill pathogens, including bacteria, viruses, molds
and fungi. For example, the main component of Dubonvec disinfectant is the potassium bisulfate trisalt complex, which kills pathogens by increasing the permeability of cell membranes, causing the loss of enzymes and nutrients, and the dissolution and rupture of pathogens.
2. Bleach: Potassium persulfate is oftenused as a desizing agent or active bleach in the textile industry. It can effectively remove the paste and color from the fabric to achieve a bleaching
effect. Under certain conditions, the aqueous solution of potassium persulfate can decompose to produce hydrogen peroxide, which further plays the role of bleaching.
3. Food bleach: Potassium persulfate canalso be used as food bleach. In food processing, it can destroy or inhibit food color formation factors, make its color fade or avoid food Browning. However, it should be noted that the use of food bleach needs to strictly comply with relevant food safety standards and regulations to ensure the health and safety of consumers.
4. Water treatment disinfectant: Potassiumpersulfate can also be used for disinfection in the water treatment process, and its strong oxidation performance helps to kill microorganisms in water and ensure the health and safety of water quality.
5. Low temperature disinfectant: Potassiumpersulfate can also be used to prepare low temperature disinfectant. The results show that the low temperature disinfectant prepared with potassium bisulfate disinfectant and sodium chloride solution coolant still maintains liquid state at -20℃, without precipitation or crystallization, showing good stability and disinfection effect.
These applications demonstrate thediversity and importance of potassium persulfate in the field of disinfectants and bleach, not only to provide effective disinfection and bleaching solutions, but also to meet the needs of applications under specific conditions. With the
development of technology and changes in market demand, the application of potassium persulfate in these fields may be further expanded and deepened.
