Technical Field
The invention relates to the technical field of disinfectant, in particular to hypochlorous acid disinfectant and a preparation method thereof.
Background
Sodium hypochlorite is a strong electrolyte, firstly ionizes in water to generate hypochlorite ions, and if the hypochlorite ions hydrolyze, hypochlorous acid can be generated, the hypochlorite ions are further decomposed to generate nascent oxygen, and the nascent oxygen has very active chemical property and very strong oxidizing power and plays a great role in the disinfection process. The disinfection principle of the hypochlorous acid disinfectant is that hypochlorous acid is subjected to oxidation-reduction action with bacterial cell walls and virus shells to crack germs; because of unstable decomposition to generate nascent oxygen, the extremely strong oxidizing property of the nascent oxygen denatures the proteins of thalli and viruses, thereby killing pathogenic microorganisms; chloride ions can significantly alter the osmotic pressure of bacteria and virions, resulting in their loss of activity and death.
Antibiotics have been the primary drug to treat bacterial infections since the discovery of penicillin in the 40 th century. With the widespread use of antibiotics, drug-resistant strains have become pathogenic bacteria which are common in clinical infections, and the generation and increasing of multi-drug resistance phenomenon make the treatment of bacterial infections very challenging. For infection caused by intracellular bacteria, antibiotics must first bind to target pathogenic bacteria in the cell to act, and thus the antibacterial effect of the antibiotics is affected by many factors, including the concentration, distribution and duration of action of the antibiotics in the cell. Therefore, the method carries out certain chemical modification on the antibiotics, optimizes the intracellular pharmacokinetic parameters of the antibiotics, and has great significance for expanding the application of the existing antibiotics in the treatment of infection caused by intracellular bacteria.
