Manufacturing process and use of industrial hydrochloric acid
Industrial hydrochloric acid is usually made by letting chlorine and hydrogen undergo a chemical reaction in corrosion-treated cylinders to produce hydrogen chloride, which is then injected into water. Because the chemical reaction will produce some iron trichloride part of the impurities.

Outstanding Advantages and Detailed Uses of Sodium Hypochlorite Disinfection Solution
Sodium hypochlorite disinfectant has the following outstanding advantages compared with other disinfectants: I. Pure quality The use of edible salt and water as raw materials, no impurities and other substances Disinfection effect is precise, efficient and fast 1. chlorine disinfectant, is a highly effective chemical disinfectant. 2-10 minutes to kill a variety of microorganisms, including bacterial spores and fungal spores, can inactivate all viruses; can effectively prevent hepatitis, venereal disease, dysentery, cholera, typhoid fever and other diseases. 2. Low effective concentration. At the concentration of 5ppm, it has the exact disinfection effect. Safety and environmental protection 1.The effective chlorine content of the disinfectant solution produced by sodium hypochlorite disinfectant generator is from 1200ppm to 5000ppm.The concentration range of sodium hypochlorite solution is enough for disinfection, but safe enough for users. 2. Sodium hypochlorite disinfectant solution is highly efficient, high speed, broad spectrum, non-toxic, harmless, and free from residue contamination. 3. Sodium hypochlorite disinfectant is relatively stable, but it is very easy to decompose when it meets water, heat and light. It can be decomposed rapidly after disinfection and has no harm to the environment. 4. There is no free chlorine in sodium hypochlorite disinfectant, and it will not react with other organic substances to form a class of carcinogenic chlorinated organic compounds such as trichloromethane, carbon tetrachloride, dioxin. Fourth, comprehensive disinfection Sodium hypochlorite disinfectant can be widely used in five aspects, including human health care, such as clothing, food, housing, and so on, because of its pure quality and precise effect. Wide range of uses Sodium hypochlorite disinfectant also has the degradation of pesticide residues, anti-itching, cleaning, bleaching, deodorizing, antiseptic, preservation of freshness, prevention of mosquitoes and flies breeding and other aspects. Sodium hypochlorite disinfectant solution detailed use: Family: Can be used in all aspects of the family, can be in contact with water most of the items of the disinfection treatment. Human health care aspects 1. Disinfection, hemostasis, anti-inflammatory and anti-infection of small wounds, traumas, scratches and bruises on the body surface. 2. Prevention and auxiliary treatment of skin itching. 3. Prevention and auxiliary treatment of vulvar itching 4. Treatment of gray nails and onychomycosis 5. Treatment of foot fungus 6.

Disinfection, cleaning and deodorization of pet houses or bird cages 14. Disinfection, cleaning and deodorization of pets Disinfection of daily necessities 1. Disinfection and cleaning of towels and washcloths 2. Sanitize and clean toothbrushes 3. Disinfection and cleaning of dentures 4. Sterilization and cleaning of telephone handsets 5. Bottles, pacifiers, toys (except metal toys) and other disinfection, cleaning sodium hypochlorite disinfectant and other disinfectants compared to the following outstanding advantages: I. Pure quality The use of edible salt and water as raw materials, no impurities and other substances
A study on the dosage of sodium hypochlorite and sodium nitrosoferricyanide in the measurement of ammonia nitrogen in water
1 Ammonia Nitrogen Experiment 1.1 Principle of the method In the presence of sodium nitroso ferrocyanide, ammonium reacts with salicylate and hypochlorite ions to form a blue compound with maximum absorption at wavelength 697nm.
Does sodium hypochlorite reduce the incidence of emergencies during root canal treatment?
Endodontic interappointment emergencies (EIAE) are pain or discomfort of varying degrees in the affected area of the tooth during root canal treatment, and in severe cases, localized swelling or even acute cellulitis may occur, mostly after root canal preparation. Currently, it is recognized that microbial infection is the main cause of EIAE, therefore, infection control has become a very important part of the root canal treatment process. In order to control infection and prevent EIAE, the surgeon's operations need to be performed in a sterile environment, while removing as much infected material remaining in the root canal as possible. Rubber-barrier hygromancy provides complete isolation of the affected tooth from the oral cavity and is the most thorough hygromancy method available for root canal treatment. Among the commonly used rinsing solutions, sodium hypochlorite is one of the most effective root canal rinsing solutions with its antibacterial and dissolving effects on necrotic pulpal tissues. In this study, we investigated whether the use of sodium hypochlorite rinsing combined with rubber barrier wet isolation in root canal therapy could have the clinical effect of reducing the incidence of emergencies during root canal therapy.
