Problems solved by technology

Weakly acidic hypochlorous acid water is weakly acidic water with hypochlorous acid as the main component. Neutrophils responsible for human immune function produce hypochlorous acid, which dominates biological immunity and is an indispensable active molecule even for humans; especially For the rapid spread of the new coronavirus, slightly acidic hypochlorous acid has become an indispensable disinfectant at home, but due to the efficiency of electrolysis, the supply of slightly acidic hypochlorous acid water is limited

Embodiment 1

[0041] A preparation method of high-performance hypochlorous acid is obtained by preparing sodium chloride and water through electrolysis equipment. The mass concentration of described sodium chloride is 1%, and current density is 0.2A / cm 2 .

[0042] The electrolysis equipment adopts the Danish Clean Water hypochlorous acid generator, the model is T25 series; the DanishClean Water hypochlorous acid generator is pretreated and then electrolyzed; the pretreatment of the anode includes the following steps: 1) carbon nanometer Add the tube to isopropanol and sonicate for 30 minutes, then add ruthenium trichloride, tin tetrachloride, IrCl 3 , and stir evenly to obtain a pretreatment composition; 2) uniformly coat the pretreatment composition on the anode, and bake it at 400 degrees Celsius for 30 minutes to obtain. Wherein, the carbon nanotubes described in step 1) are multi-walled carbon nanotubes, including multi-walled carbon nanotubes with a length of 0.5-2 microns, multi-wa...

Embodiment 2

[0044] A kind of preparation method of high-performance hypochlorous acid, specific embodiment is the same as embodiment 1, and difference is that described anode carries out pretreatment and comprises the following steps: 1) isopropanol is added ruthenium trichloride, tin tetrachloride, tin tetrachloride, IrCl 3 , and stir evenly to obtain a pretreatment composition; 2) uniformly coat the pretreatment composition on the anode, and bake it at 400 degrees Celsius for 30 minutes to obtain. Wherein, the molar ratio of ruthenium, tin, and iridium in the pretreatment composition in step 1) is 1:4:1.5; the coating amount of the pretreatment composition on the anode is 6.8g / m 2 .

Embodiment 3

[0046] A kind of preparation method of high-performance hypochlorous acid, specific embodiment is the same as embodiment 1, and difference is that, described anode carries out pretreatment and comprises the following steps: 1) graphene is added in isopropyl alcohol ultrasonic 30 minutes, then add Ruthenium trichloride, tin tetrachloride, IrCl 3 , and stir evenly to obtain a pretreatment composition; 2) uniformly coat the pretreatment composition on the anode, and bake it at 400 degrees Celsius for 30 minutes to obtain. Wherein, the molar ratio of ruthenium, tin and iridium in the pretreatment composition in step 1) is 1:4:1.5; the concentration of the graphene is 1 mg / mL. The coating amount of the pretreatment composition on the anode is 6.8g / m 2 .

Abstract

The invention belongs to the technical field of hypochlorous acid, and particularly relates to a preparation method of high-performance hypochlorous acid. According to the method, the high-performancehypochlorous acid is prepared from chlorine-containing metal salt and water through electrolysis equipment. The effective chlorine concentration of the high-performance hypochlorous acid prepared bythe method is 200 to 800 mg / L; the high-performance hypochlorous acid can effectively kill bacteria, fungi, viruses and spores, is small in molecule and free of charges, so that the high-performance hypochlorous acid is extremely easy to diffuse and permeate to simultaneously generate an oxidation effect on the inner side and the outer side of the bacteria, the sterilization speed and the sterilization effect are obviously higher than those of common disinfectant fluid, and an environment in which resistant bacteria cannot breed can be generated.

Description

technical field [0001] The invention belongs to the technical field of hypochlorous acid, and more specifically, the invention relates to a preparation method of high-performance hypochlorous acid. Background technique [0002] Hypochlorous acid has been demonstrated internationally as one of the most efficient disinfection and sterilization products. At present, the methods for producing hypochlorous acid mainly include: electrolysis of dilute hydrochloric acid, proportioning of weak acid and sodium hypochlorite, and electrolysis of brine. Among them, the method of producing hypochlorous acid by electrolysis of brine is increasingly recognized and favored by the market because of the absence of chemicals in the raw materials and production process, safety and environmental protection, and will not pose a threat to people, equipment and the environment. the trend of. At present, the production of hypochlorous acid disinfectant by electrolysis mostly uses a diaphragm electr...
