What can be used to remove mercury and how to deal with mercury

I don't know what you do with the scattered, but the scientific method is to use sulfur, sulfur to react with it, to form another substance, to reduce its toxicity.

There are two types of mercury poisoning: acute poisoning: acute poisoning has symptoms such as abdominal pain, diarrhea, and hematuria; Chronic poisoning is mainly manifested by oral inflammation, muscle tremors and mental disorders.

Turn off all heating devices in the room and open windows for ventilation. Then put on gloves and use a small shovel to collect the mercury and bury it deeply, or sprinkle some sulfur powder on it, the reaction of sulfur and mercury can produce mercury sulfide that is not easily soluble in water, and the harm will be greatly reduced.

Since mercury can evaporate into a gaseous state at room temperature, it is easy to be sucked into the respiratory tract and cause poisoning, so it is best to wear a mask when handling mercury scattered on the ground. If the wound touches mercury, it should be examined by the poison prevention and control department of the hospital, and then the poisoning phenomenon is carried out**.

If there is no sulfur at home, the collection and treatment method of falling mercury is to use a moist small cotton swab or tape paper to collect the mercury spilled on the ground, put it into a small bottle that can be sealed, such as a plastic bottle such as a beverage bottle, and add a small amount of water to the bottle, and write "waste mercury" and other identifying words on the bottle, and hand it over to the waste liquid management personnel of the unit or community neighborhood committee for disposal or send it to the environmental protection department for special treatment.

There is sulfur, which can be used to remove mercury that cannot be collected. For mercury that cannot be completely collected on the ground, some sulfur powder can be sprinkled to reduce the toxicity of mercury. Because sulfur powder can combine with mercury to form mercury sulfide compounds that are difficult to volatilize, it prevents mercury from volatilizing into the air and harming human health.

In general, mercury does not evaporate quickly, and if the mercury thermometer is broken at home and treated cleanly, and the ventilation conditions in the home are relatively good, it generally does not cause mercury poisoning. Sprinkle some sulfur powder on top... I am cleaning.

In particular, it is important not to pour the collected mercury into the sewer to avoid polluting the underground water source. If mercury seeps into groundwater, people drink water that contains heavy metals, which can be harmful to human health. Hope.

Sulfur powder is cheaper, and silver nitrate is more expensive.

If you want to clean up mercury, you need to do the following:1. Quickly take children and pets out of the room, and remember not to use vacuum cleaners, brooms, or rags to clean up mercury.

2. Clean up the mercury under the condition of keeping the room ventilated, if the room can adjust the temperature, try to reduce the room temperature, which can reduce the volatilization of mercury and promote condensation. If the mercury falls on a smooth ground such as tiles, you can use a cardboard shell, scraper, etc., and scrape from the periphery of the scattered part close to the ground to the center, you can see that the mercury balls will gradually gather into large balls, and then gently shovel up the mercury balls and close them into a plastic bag. If mercury is scattered on rough surfaces such as carpets or on beds, you can tape them and then close them with tape into a plastic bag, which is recommended to be layered in layers to prevent breakage and leakage.

3. Keep the room ventilated for at least 24 hours, open the fan and doors and windows as much as possible, do not enter the room during the ventilation process, if you do not properly handle the mercury or have cleaned the ground with a mop, etc., it is recommended to extend the ventilation time for at least 24 hours.

4. Treat mercury contaminated materials, for clothes and shoes contaminated with mercury, discarding is the best choice, or cleaning up many times, hanging in a place without children and good ventilation for 3-5 days, to ensure that mercury volatilization is complete, remember not to directly use the washing machine or dryer to wash clothes that may be contaminated with mercury.

If only the thermometer is broken, the mercury in it, as long as people do not touch it, especially the hands and other places where there are wounds, do not touch it, and do not swallow it in the mouth, there is generally no problem, and it will not cause much toxic effect on the human body due to the vapor formed by the evaporation of mercury, you can rest assured; If the mercury thermometer is broken and the mercury drips on the soil, if you want to deal with it, you can remove part of the soil layer or dig up the soil and turn it over to bury the mercury; If it falls on hard floors such as cement floors and tiled floors, you can also mix wheat flour (flour) with an appropriate amount of water to form a dough and press it on top of the mercury to stick the mercury away. It's easier to handle.

Mercury is a chemical element, the element symbol HG, the 80th position of the periodic table, in the periodic table of chemical elements in the 6th period, the IIB group, commonly known as mercury, as well as "Bai Li, Yinnu, Lu, Shen Jiao, Yuan Shui, Lead Essence, Liuzhu, Yuan Zhu, Red Mercury, Sand Mercury, Ling, Huobao, Ziming" and other aliases, is the only metal that exists in a liquid state at room temperature and pressure (in a strict sense, gallium (symbol GA, element 31) and cesium (symbol CS, element 55) at room temperature (and also in a liquid state). Mercury is a silvery-white, shiny, heavy liquid that is chemically stable and insoluble in acids or alkalis. Mercury can evaporate at room temperature, and mercury vapor and mercury compounds are often highly toxic (chronic).

Mercury has been used for a long time and has a wide range of uses. [1] In medieval alchemy, along with sulfur and salt, they were called the sacred three elements of alchemy.

If you have protective equipment at home, such as protective gloves and masks, wear them as soon as possible. Then use the collection tools available at home, such as syringes, droppers, small shovels, soaked cotton swabs, small brushes, adhesive tape, etc., to collect the mercury and place it in a small bottle that can be sealed, and add a small amount of water to the bottle to seal it, and then hand it over to the environmental protection department in the community for special treatment. At the same time, open windows for ventilation to help reduce the concentration of mercury in the air.

1. Handlers should wear hats, masks and gloves; If the mercury droplets are large, you can roll them into a tube with slightly stiff paper, or collect them with tin foil, tape paper, and moistened cotton swabs, and pack the mercury droplets in a sealed bottle; It is worth noting that mercury is insoluble in water, so the water seal cannot effectively prevent its volatilization, and the liquid level can be covered with glycerin or 5% sodium sulfide solution to prevent the evaporation of mercury vapor.

2. When the mercury drips in the gap or is very fine, an appropriate amount of sulfur powder can be taken to cover it, so that it can produce a chemical reaction to form sulfide mercury, and clean it after 3-4 hours, the sulfide mercury is solid and cannot evaporate, so it reduces the harm to the human body; Or spray with 20% ferric chloride (10% bleach solution), at this time the mercury flowing out forms an alloy of non-toxic mercury and iron, which is placed for 1 hour and then cleaned.

Chemical properties: soluble in nitric acid and hot concentrated sulfuric acid, mercury nitrate and mercury sulfate are generated, respectively, and mercury salt appears in excess of mercury. It can dissolve many metals and form alloys, which are called amalgam. The valency is +1 and +2.

Similar to silver, mercury can also react with hydrogen sulfide in the air. Mercury has a constant coefficient of bulk expansion, is less metally active than zinc and cadmium, and cannot displace hydrogen from acid solutions. Generally, mercury compounds have valencies of +1 or +2, with only mercury tetrafluoride being the only mercury compounds at +4 valence, and no mercury compounds at +3 valence.

1. Open the window to ensure indoor air circulation.

The reason for opening the window is that the mercury volatilizes quickly at room temperature, and even if it is cleaned up in time, some of the mercury vapor will still volatilize into the air, so it is necessary to open the window for ventilation to reduce the density of mercury vapor in the air. At the same time, because you have to deal with mercury, which means that you can't leave the mercury vapor environment immediately, you should wear a mask first to reduce the amount of mercury vapor inhaled.

2. Quickly collect the mercury beads scattered on the ground.

Use a small damp cotton swab or tape paper to gently glue the mercury spilled on the ground or collect it with other professional tools to gather it in one place (the mercury forms a larger ball when it comes into contact with each other), then collect it into a vial, add a small amount of water to it, and close the lid. If necessary, you can make a mark on the bottle to indicate that it is mercury to avoid misuse by uninformed people.

3. The residual mercury is cleaned up with sulfur powder.

For mercury that falls on the ground and cannot be completely collected, sprinkle some sulfur powder on the place where mercury may be sprinkled (sulfur and mercury can react to form mercury sulfide that is not easily soluble in water, and the harm will be greatly reduced), and then collect the sulfur powder into a plastic bag and clean it for a few days to reduce mercury toxicity. The combination of sulfur powder and mercury can form a mercury sulfide compound that is difficult to volatilize, preventing mercury from volatilizing into the air and endangering human health.

4. Continue to open the window for 24 hours ventilation.

Continuously open windows for 24 hours for ventilation, and sealed bags containing mercury particles can ask local environmental authorities what to do with them, or bury them deep in the soil so that mercury does not volatilize. Remember not to pour it directly down the drain or into the trash with other garbage.

If the amount of mercury is small, it can be covered with sulfur powder and then removed. When the amount of mercury is large, you can use waterproof paper to collect the mercury, put it in a sealed box for preservation, open the window for ventilation, so that the small amount of mercury remaining on the ground can quickly volatilize. The mercury collected should be sent to a professional institution for treatment and should not be poured down the drain, otherwise it may contaminate the water source.

Wear a mask during the handling process to avoid inhaling mercury vapor.

If the mercury leakage is not treated in time, resulting in its rapid evaporation, a large amount of inhalation by the human body, dizziness, malaise, fever, stomatitis, nausea, abdominal pain, diarrhea and other symptoms may occur, severe can lead to acute pulmonary edema and acute renal failure, once mercury poisoning should be removed from the environment as soon as possible, and sent to the hospital in time**.

How to remove mercury from the environment.

1. Adopt technical measures: the use of low-temperature enthalpy gasification, evaporation, activated carbon adsorption, membrane separation, ion exchange, solvent extraction and other technologies can effectively remove mercury.

2. Physical methods: Mercury can be effectively removed by using physical methods such as oil film separation, ion exchange, solvent extraction, wet extraction, and chemical extraction.

3. Biological methods: Biological methods such as microbial technology and plant absorption technology can effectively remove mercury.

4. Chemical methods: Oxidation, discharge and other chemical methods can effectively remove mercury.

Sulfur powder is used for absorption, which can form a very stable mercury sulfide, and if it is steam, it is absorbed by iodine vapor.

Mercury is a chemical element, commonly known as mercury (mercury can also be written as 龾).Its chemical symbol is Hg, and its atomic number is 80It is a heavy, silvery-white liquid transition metal. Because of this property, mercury is used to make thermometers.

Pure mercury is toxic, but its compounds and salts are very toxic and can cause brain and liver damage when taken orally, inhaled, or after exposure. As a result, most of today's thermometers use alcohol instead of mercury. Some medical thermometers still use mercury because of its high accuracy.

At standard air pressure and temperature, the biggest danger of pure mercury is that it easily oxidizes and produces mercury oxide, which tends to form small particles and increase its surface area.

Although pure mercury is less toxic than its compounds, it is still a dangerous pollutant because it forms organic compounds in living organisms.

The most dangerous mercury organic compound is C2H6HG, which can be lethal when exposed to just a few microliters.

Mercury is a poison that can accumulate in living organisms, and it is easily absorbed by ** as well as by the respiratory and digestive tracts. Minamata disease is a type of mercury poisoning. Mercury damages central nervous system tissue, which has adverse effects on the mouth, mucous membranes, and teeth.

Prolonged exposure to high mercury can lead to brain damage and death. Despite the high boiling point of mercury, the saturated mercury vapor at room temperature has reached several times the toxic meter.

Therefore, special care should be taken when handling mercury. Containers containing mercury should be particularly protected from spillage or evaporation, and heating of mercury must be carried out under a well-ventilated and well-filtered hood. In addition, some mercury compounds are automatically reduced to pure mercury, which evaporates and is often overlooked.

The specific cleaning method is as follows:

1. Once the mercury supplies are broken, the mercury will form a sphere and roll off, wear a mask, turn off all heating devices in the room, and open the window for ventilation.

2. Wear gloves and sprinkle some sulfur powder on the polluted place of bed sheets, the reaction of sulfur and mercury can produce mercury sulfide that is not easily soluble in water, and the harm will be greatly reduced.

3. Since mercury can evaporate into a gaseous state at room temperature, it is easy to be inhaled into the respiratory tract and cause poisoning, so it is best to wear a mask when dealing with scattered mercury.

4. After the bed sheet cover contaminated by mercury is cleaned, it is best to dry it in the sun for a period of time before use, if it cannot be guaranteed to be cleaned, it can be cleaned off separately.

PS: Mercury is the only metal in a liquid state at room temperature and pressure, the scientific name is mercury, there is evaporation at room temperature, mercury is a highly toxic heavy metal pollutant in the environment, it is difficult to be discharged after entering the organism, and it is a serious threat to human health. Care must be taken when post-processing contaminated sheets.

Regarding whether it will be absorbed into the body, this dose of the thermometer will not cause mercury poisoning, do not need to be too nervous, pay attention, drink more water, eat more fruits and vegetables, although mercury is toxic, but only under specific volatile conditions volatilization into gas through breathing into the internal organs will cause problems.
