Preparation and sterilization principle of sodium hypochlorite liquid:
Sodium hypochlorite (NaClO) is obtained by electrolysis of salt water with the titanium anode of the generator. The reaction is as follows:
NaCl+H2O→NaClO + H2↑
Sodium hypochlorite is hydrolyzed in water to form hypochlorite and sodium hydroxide, and the reaction is as follows:
NaClO+ H2O→HClO + NaOH
The effective ingredient of sodium hypochlorite disinfectant for disinfection is HClO, which is dissociated in water, and the reaction is as follows:
HClO ⇋ H+ +ClO-
HClO will be dissolved due to the influence of some impurities or light in the water. The reaction is as follows:
2HClO ⇋ 2HCl+ O2↑
1. Applications in papermaking, textiles and water treatment:
Sodium hypochlorite liquid is a highly efficient oxidant. It exists in two forms of HClO and ClO in water. HClO is extremely unstable and easy to decompose into O2. The new ecological oxygen has a strong oxidation capacity, which can destroy the organic pigment groups and fade the colored materials. Therefore, it is used to bleach pulp in paper industry and bleach fabric in textile industry. In addition, sodium hypochlorite is used in inorganic chemical industry, dyestuff, metallurgy, medicine, light industry, agriculture and animal husbandry. In the field of industrial water and drinking water treatment, when sodium hypochlorite solution can be used as a bactericide and algaecide, add water to dilute the industrial sodium hypochlorite solution, and directly add it to the water system with a corrosion resistant pump After sodium hypochlorite enters the water, hypochlorite (HClO) is formed, which is the main effective ingredient for killing bacteria and algae. HClO can completely oxidize and eliminate the odorous inorganic substances in the water, purify the water, protect the industrial water delivery equipment, make the drinking water quality meet the national standards, and ensure human health.
2. Application in air disinfection:
The hospital is a place where various patients are clustered for treatment, and also a place where pathogenic microorganisms inhabit and breed and where infected people gather. A large number of pathogenic microorganisms in the air can invade the body through respiratory tract, skin, mucous membrane and other channels with dust and droplets, which is an important cause of hospital infection. The clinic, ward, diagnosis and treatment rooms and treatment rooms are disinfected with spray of sodium hypochlorite disinfectant. Since 1996, the air spray disinfection with sodium hypochlorite disinfectant has been tried. After disinfection, the results of air bacteria content reached the specified standard, so effective air disinfection can reduce the incidence of cross infection in hospitals. Sodium hypochlorite disinfectant is a kind of effective chlorine and surfactant, which has a strong killing effect on the increase of bacteria, spores, viruses and tuberculosis bacteria. After the sodium hypochlorite air spray, the content of bacteria in the air decreases significantly. It is a chlorine containing disinfectant made of pure natural materials, which can penetrate various organic substances, quickly kill a variety of bacteria and viruses. It is a highly effective disinfectant with quick action and good effect.
3. Application in killing algae in circulating water of air compressor:
When sodium hypochlorite is put into the circulating water tank, it can penetrate the cell wall of bacteria to kill bacteria and algae. The killed algae fell off from the corrugated plate and pool wall after death, forming sludge and sinking into the pool bottom, thus improving the heat exchange effect of the existing cooling tower. During the interval of dosing, the residual sodium hypochlorite in the water has a certain inhibition on the formation of bacteria and algae, which can also slow down the rate of algae re formation.
The addition of sodium hypochlorite to the cooling circulating water for disinfection can indeed effectively kill the breeding bacteria and algae and play a great role in improving the heat transfer effect of the cooling tower. Sodium hypochlorite is relatively economical as a bactericidal disinfectant, and has a broad application prospect.
4. Application in banana open tissue culture:
The key to the open tissue culture technology of plants is to find effective bacteriostatic agents. At present, research on the use of antibiotics, pesticides, household disinfectants, plant extracts, food additives, etc. as bacteriostatic agents has been well conducted, but there is no report on the use of sodium hypochlorite as bacteriostatic agent in China, and only the use of sodium hypochlorite in open groups of several ornamental plants has been reported abroad. Sodium hypochlorite is one of the most commonly used chlorine containing disinfectants. It has broad bactericidal spectrum, rapid action, low toxicity, low price, and strong killing ability against viruses, bacteria, fungi and spores.
According to the literature, sodium hypochlorite can be used as an bacteriostatic agent for banana open culture, with the concentration of 0.01%~0.02% being the best.
Analysis and Application of Sodium Hypochlorite Solution Disinfectant in Water Plant
Sodium hypochlorite liquid is put into water and hydrolyzed instantaneously to form hypochlorite and hypochlorite radical. As hypochlorite is a small neutral molecule without charge, it can quickly spread to the surface of negatively charged bacteria (viruses) and penetrate into bacteria through the cell wall of bacteria. Hypochlorite has extremely strong oxidation to destroy the enzyme systems such as proteins on bacteria and viruses; Thereby killing pathogenic microorganisms.
adverse reaction
Sodium Hypochlorite Liquid, as a widely used disinfectant and bleach, plays an important role in various fields such as healthcare, hygiene, industry, and household cleaning. However, its strong oxidizing and corrosive properties also determine that it may cause a series of adverse reactions during use.
Skin adverse reactions
Stimulating response
Sodium hypochlorite solution has significant irritation to the skin, especially in high concentration solutions. After direct contact with the skin, it may cause local redness, pain, and burning sensation, which is a direct reaction of the skin to chemical stimulation. Low concentration solutions may only cause mild discomfort, while high concentration solutions may lead to impaired skin barrier function and more severe irritation symptoms.
Corrosive damage
The strong oxidizing property of sodium hypochlorite can damage the protein structure of the skin, leading to tissue necrosis. Long term exposure or high concentration exposure may cause blisters, ulcers, and even deep tissue damage to the skin. This type of injury not only causes severe pain, but also heals slowly and is prone to leaving scars.
Allergic reactions
Some people have allergic reactions to sodium hypochlorite, manifested as erythema, papules, blisters at the contact site, accompanied by severe itching. Allergic reactions may occur rapidly or gradually manifest after multiple exposures. In severe cases, systemic allergic symptoms such as urticaria, angioedema, and even anaphylactic shock may occur.
Chronic effects of long-term exposure
Workers who have been repeatedly exposed to sodium hypochlorite solution for a long time, such as cleaners and disinfectant producers, may experience chronic skin damage such as excessive sweating on their palms, thinning of their nails, and hair loss. These symptoms are related to the long-term irritation and damage of sodium hypochlorite to skin appendages.
Mucosal adverse reactions
Eye irritation and injury
After sodium hypochlorite solution splashes into the eyes, it can immediately cause eye pain, tearing, photophobia, and conjunctival congestion. High concentration solutions may cause corneal epithelial detachment, corneal opacity, and even visual impairment. The severity of eye injury is closely related to solution concentration and contact time.
Oral and throat irritation
After ingesting or inhaling the aerosol of sodium hypochlorite solution, there may be a burning sensation, pain, and difficulty swallowing in the oral and throat mucosa. In severe cases, mucosal edema and ulcers may occur, affecting breathing and eating.
Respiratory mucosal irritation
After inhaling sodium hypochlorite mist, the respiratory mucosa may be stimulated, which can cause coughing, wheezing, and difficulty breathing. Long term exposure to low concentration sodium hypochlorite aerosols may lead to respiratory diseases such as chronic bronchitis and decreased lung function.
Gastrointestinal mucosal injury
After ingesting sodium hypochlorite solution by mistake, the digestive mucosa is strongly stimulated and corroded, and symptoms such as burning pain, nausea, vomiting, vomiting blood, and black stool may occur in the mouth, throat, esophagus, and stomach. Severe cases can lead to gastrointestinal perforation, peritonitis, and even shock and death.
