Hydrogen peroxide industrial online analyzer product characteristics and storage protection precautions

Residual chlorine means that after chlorine is put into water, in addition to the consumption of a part of the chlorine with the water bacteria, microorganisms, organic matter, inorganic substances and other effects, there is still a part of the chlorine

Residual chlorine can be divided into combined residual chlorine (refers to the chlorine and ammonia compounds in water, including NH2Cl, NHCl2 and NHCl3, NHCl2 is more stable, good sterilization effect), also known as binding residual chlorine; Free residual chlorine refers to OC1+, HOCl, Cl2 in water, which has fast bactericidal speed, strong bactericidal power, but disappears quickly), also known as free residual chlorine; Total residual chlorine is the sum of combined residual chlorine and free residual chlorine.

Potential hazards of chlorine in water and its residual chlorine to human body

1. What is the main way of disinfection and sterilization of tap water at present?

A: The current purification methods of tap water in China are chlorine sterilization; Developed countries and regions of the world tap water purification: ultraviolet and ozone technology sterilization.

2. Why should chlorine be added to tap water?

A: Tap water should originally be a kind of both sanitary and safe drinking water, but due to environmental pollution, resulting in a large number of harmful substances such as bacteria in the water, in order to inhibit and kill the bacteria in the water, chlorine is added in the process of water treatment.

3. What harm does chlorine do to human body?

A: Chlorine is a serious hazard to the human body. It can irritate the eyes, nose, throat and upper respiratory tract. Cause acute pulmonary edema and pneumonia, high concentration can paralyze the respiratory center, appear "flash death". Long-term inhalation of low concentrations of chlorine can cause chronic poisoning, resulting in the production of a large number of free radicals in the body, accelerating the speed of human aging. The main conditions are rhinitis, chronic bronchitis, emphysema, cirrhosis of the liver, atherosclerosis and even cancer.

When chlorine is added to water, it will make your hair dry, broken and split, as well as bleach your skin, peel off the skin layer and cause itch itch itch hypersensitivity. When chlorine is heated, it produces carcinogenic substances such as trichloromethane with organic rot in water.

4. What is the effect of water containing residual chlorine on cleaning vegetables, fruits, grains, etc.?

A: Chlorine will destroy the vitamins, minerals and other nutrients in vegetables, fruits and grains, and seriously affect the absorption of nutrients by the human body.

5. How does residual chlorine enter the human body?

A: The chlorine used in tap water is easily and quickly absorbed to any oxidized surface with pores, such as skin, nostrils, mouth, lungs, hair, eyes, meat, vegetables, fruits and vegetables.

6. Why is residual chlorine easily absorbed through human skin?

A: Since the surface of human skin is covered with pores and sweat glands, residual chlorine can easily be absorbed into human skin through these fine pores when it comes into contact with tap water.

7. What is the harm of taking a bath with residual chlorine for a long time?

A: Take a bath with tap water containing residual chlorine, 40% of the total chlorine gas in the bathroom is inhaled through the respiratory tract, 30% is absorbed by the skin, is usually through drinking into the body of chlorine 6 ~ 8 times, light itching, accumulated over time to middle-aged cancer rate will increase by 30%;

8. Why say tap water after boiling more harm?

Answer: the tap water to be boiled, chlorine after heat and water organic decay to produce trichloromethane and other carcinogens, trichloromethane will increase 3 ~ 4 times than tap water, if the residual chlorine can not be removed, our daily drinking coffee, tea or soup, after heating and boiling drinking; Our bodies are 3 ~ 4 times more carcinogens.

9. Long-term drinking water containing residual chlorine can cause what disease?

A: Heart disease, coronary atherosclerosis, anemia, bladder cancer, liver cancer, rectal cancer, high blood pressure and allergies.

10. What is the harm of residual chlorine to children?

A: When bathing children with tap water, chlorine will make hair dry, broken and bifurcated. It will also make skin bleach, skin layer fall off and produce itch itch itch hypersensitivity; When chlorine interacts with organic matter, such as sweat, it causes nitrogen trichloride to form in the surrounding air, which can damage the eyes and throat. When inhaled through the respiratory tract, chlorine damages respiratory cells (Clara cells), which can lead to asthma and emphysema.

11. Residual chlorine to pregnant women what harm?

A: Long-term drinking of chlorinated tap water by pregnant women will affect the growth of fetal heart and lungs, which may lead to arrhythmia, heart failure and lung dysfunction in newborns.

12. Residual chlorine to the elderly what harm?

A: It can lead to atherosclerosis, heart failure, arteriosclerosis, heart disease, bladder cancer, liver cancer, rectal cancer, high blood pressure.

Notes for storage and protection of hydrogen peroxide industrial online analyzer:

1. The glass electrode is strictly prohibited to be exposed in the air for a long time;

2. Glass electrodes are strictly prohibited from being placed in distilled water or deionized water for a long time. Prolonged placement in distilled or deionized water leads to ion leakage from the bulb or reference solution of the glass electrode, so the electrode reaction retardation life is shortened.

3. When not used for a long time, the glass electrode head should be covered with the electrode protection cap, and the cap should be added with saturated solution.

4. The surface cleaning of the glass electrode is very important for obtaining the correct measurement data. If there are pollutants attached to the surface of the electrode, you can use clean water to wash it, and do not use your hands or other hard objects to wipe it
