Activated charcoal purifies the air.
Activated carbon adsorption method is a method that uses porous activated carbon to make one or more substances in water be adsorbed on the surface of activated carbon and remove, including dissolved organic substances, synthetic detergents, microorganisms, viruses and a certain amount of heavy metals, and can decolorize, deodorize, and purify the air.
Activated carbon, sulfonated coal, zeolite, coke, etc. are commonly used adsorbents in water treatment, and the activated carbon lattice forms developed pores of different shapes and sizes after activation, which greatly increases the specific surface area and improves the adsorption capacity. The effective radius of the fine pores of activated carbon is generally 1-10000nm, the radius of small pores is less than 2nm, the radius of transition pores is generally 2-100nm, and the radius of macropores is 100-10000nmThe pore volume is generally, and the transition pore area is generally; The macropore volume is generally.
Activated carbon is a very fine carbon particle with a large surface area, and there are even finer pores in the carbon grain - capillaries. This capillary has a strong adsorption capacity and is in full contact with gases (impurities) due to the large surface area of the carbon particles. When these gases (impurities) touch the capillaries, they are adsorbed and purified.
The surface area of activated carbon is very important, the specific surface area of activated carbon detection data is only true and reliable by the BET method, and there are many instruments in China that can only do direct comparison detection. At this stage, the specific surface area test at home and abroad adopts the multi-point bet method, and the specific surface area determination standards formulated at home and abroad are based on the bet test method, please refer to the Chinese national standard (GB T 19587-2004) - the method for determining the specific surface area of solid substances by gas adsorption. Specific surface area detection is actually more time-consuming work, due to the difference in sample adsorption capacity, the test of some samples may take a whole day's time, if the test process is not fully automated, then the tester can not leave at any time, and to be highly concentrated, observe the dashboard, control the knob, a little carelessness will lead to the failure of the test process, which will waste a lot of valuable time of the tester.
F-SORB 2400 specific surface area tester is really able to realize the detection function of the bet method (with direct comparison method), and more importantly, the F-SORB 2400 specific surface area tester is the only fully automated and intelligent specific surface area testing equipment in China so far, its test results are highly consistent with the international level, the stability is also very good, while reducing human error, improving the accuracy of test results.

1. The principle of activated carbon adsorption is to control air pollution by using honeycomb activated carbon activated carbon, which is composed of two adsorbers in parallel, which can be used to treat intermittent exhaust, and can be used for continuous exhaust, one of which is adsorbed, and the other adsorber is desorption and regeneration, and the desorbed pollutants are emptied after catalytic combustion. The use of water-resistant activated carbon should try to avoid high temperature, because high temperature will reduce the adsorption capacity, and the adsorption effect will decrease due to the rise of temperature. At the same time, it is necessary to avoid the high dust content in the gas, because the tar dust mist will block the pores of the activated carbon, increase the wind resistance, and reduce the adsorption effect.
2. Honeycomb activated carbon has the characteristics of large area, small through-hole resistance, developed micropores, high adsorption capacity and long service life. There are a large number of micropores invisible to the naked eye in activated carbon materials, and the surface area behind 1 gram of activated carbon materials can be as high as 800 1500 square meters, and higher for special purposes. In other words, in an activated carbon particle the size of a grain of rice, the inner surface area of the micropores may be equivalent to the size of a living room.
It is these highly developed, capillary-like pore structures that make activated carbon have excellent adsorption properties. Although the speed of a molecule is affected by factors such as temperature and material, it is always in constant motion in the microenvironment. Due to the mutual attraction force between molecules, when a molecule is captured by the inner pores of activated carbon into the pores of activated carbon, more molecules will be attracted until the pores of activated carbon are filled due to the mutual attraction between molecules.

Activated carbon, which is an amorphous carbon with very strong adsorption. In daily life, many people have heard the name of activated charcoal, but they do not know what its specific function and efficacy are. The role and efficacy of activated carbon in production and life are reflected in water purification, air purification, deodorization, decolorization, etc., let's learn more about it.
1.Water purification.
Activated carbon has a strong adsorption capacity in liquids, and can absorb chlorine, heavy metals and organic matter in water to achieve the effect of purifying water.

View. 2.Purify the air.
The adsorption effect of activated carbon is also reflected in its ability to adsorb harmful gases such as formaldehyde and benzene floating in various free states in the air, and people often use it to remove formaldehyde in new houses in their lives.
3.Deodorization. A lot of new furniture and shoes that have been worn for a long time will smell, and activated carbon is just the nemesis of these odors, and putting activated carbon into these objects can achieve a good odor removal effect.

Yes, but not enough, the smoke doesn't go through the activated carbon. A fan is required to pressurize the smoked cigarette through an activated carbon filter.

Does activated carbon adsorb smoke from combustion? Yes.

All activated carbons have strong adsorption properties.
It has the function of adsorption and purification for indoor formaldehyde, benzene, radon, VOC and other gases harmful to human health, and removes various peculiar odors.
However, when placed indoors, the purification capacity is only average, mainly due to air circulation. Most of the harmful gases released are in the air. Only by allowing the air in the whole room to continuously pass through the activated carbon circulation and filtration can the comprehensive characteristics of activated carbon adsorption be brought into play.
It's like an electric stove, when it's hot, you can feel its temperature only when you stand nearby. If you want to have a fever in the whole room, you need to have it for a long time.
If you want to purify the air, the most suitable way is ventilation + local activated carbon adsorption. In a new home that you haven't moved into, I personally recommend that you buy an ozone machine, which has a good sterilization and disinfection purification effect when the power is turned on at intervals when unmanned, but few families will sit like this. The main concern is the harm of ozone to the human body indoors.
In fact, ozone is highly oxidizing and unstable, and can quickly become oxygen and be discharged outdoors.
When you move into a new home, the ozone machine can use the release of ozone in the water to disinfect dishes, chopsticks, vegetables, fruits, etc.

Generally speaking, waste activated carbon, that is, used activated carbon, has a unit, regenerated, if the use of unit regeneration, it is not suitable from the cost considerations, so it is sold to a specialized regeneration company without treatment, generally manufacturers, treatment into regenerated carbon, the adsorption capacity of regenerated carbon to decline a lot, and now there are too many domestic activated carbon. >>>More
Activated carbon has a well-developed pore structure, and the adsorbed molecules enter the adsorption pores through the macropores (R 50nm) and mesopores (2nm R 50nm) through the two transportation channels Micropores (R 2nm), and the molecules and surface groups on the pore surface are combined together by van der Waals force to complete adsorption.
