What is activated carbon?
Activated carbon (also known as Activated Carbon) is a type of charcoal that has been treated at high temperatures and is usually black, porous, and light . They are derived from coal, peat or coke,… The composition of activated carbon consists of carbon atoms in the form of graphite chips or amorphous.
Activated Carbon is also known as Activated Carbon
Activated charcoal has surprising uses such as:
- Pure water
- Air Purifier

How to distinguish activated carbon from regular charcoal?
Based on external characteristics
Activated charcoal powder is finer and drier than regular charcoal powder
If it is ingot coal, it is impossible to distinguish between activated carbon and ordinary coal. But it’s fine in powder form.
With activated carbon, their powder form is quite fine, iridescent black, uniform granules and dry.
As for regular charcoal powder, their color is black but not bright, the powder is coarse, sometimes slightly wet and the particles are uneven.
Based on the hardness of coal
Activated carbon is harder than regular charcoal
Normally, if you look at it with your eyes, it will be difficult to distinguish activated charcoal from regular charcoal. However, you can tell them apart by the hardness of each.
Activated charcoal will be harder than regular charcoal. Therefore, if you can break a stick of charcoal, it is not activated carbon because activated carbon is very hard so it is difficult to break with bare hands .
Use water to distinguish activated carbon
Activated carbon has the ability to filter water
One of the typical uses of activated carbon as well as the difference between activated carbon and regular charcoal is the ability to filter water. Therefore, you can rely on this factor to distinguish activated carbon from regular charcoal quickly.
First, you prepare a cup of dirty water . Then put each sample of coal into a cup of water, if there is foaming and the color of the water gradually clears, it is activated carbon . On the contrary, if the glass of water has no phenomenon, it is normal coal.
Burn to identify activated carbon
Regular coal when burned is very easy to catch fire and burn
Activated carbon has been processed through very high temperatures, so it is difficult to burn under normal conditions. But regular coal is very flammable.
Therefore, to distinguish activated carbon from ordinary coal, you just need to burn them at normal temperature , if the coal catches fire and is flammable, it is normal coal, otherwise, it is activated carbon.
Based on the ability to filter chlorine
Activated carbon has the ability to filter chlorine in tap water
Tap water contains a disinfectant called chlorine with an unpleasant odor for consumers. And activated charcoal has the ability to remove this smell . Therefore, you can distinguish activated charcoal from regular charcoal based on its ability to remove the odor of chlorine in tap water.
First, you prepare two cups of tap water, then put each coal sample in 2 cups of water, then smell the smell of two cups of water. If any cup has no chlorine smell, the charcoal added to that cup is activated carbon. The opposite is normal coal.
Use electricity to identify activated carbon
Activated carbon has the ability to conduct electricity
In addition to the ability to filter water, activated carbon also has the ability to conduct electricity . You can rely on this special ability of activated carbon that distinguishes them from regular charcoal.
First, you use an electrical object such as an electric tester or a light bulb, and then let the object touch the coal . If the electrical object works, it is activated carbon, otherwise, if there is no phenomenon, it is ordinary charcoal.
Types of activated carbon available today
Tubular activated carbon
As the name suggests, tubular activated carbon is produced in a large tubular shape with a diameter of 1-5 cm depending on the type. This type of activated carbon is commonly used in industry where there is a demand from larger filtration systems.
Tubular activated carbon
Activated Charcoal Tablets
Meanwhile, activated carbon in tablet form will have a short cylindrical shape, the diameter ranges from 0.8-5mm. The inside of activated carbon tablets is very sturdy, more durable than other types and the contact surface area is also larger, so it should be used to filter toxic gases well.
Activated Charcoal Tablets
Activated carbon powder
This is a conspicuous form of activated carbon, due to its ease of production, low cost, and commonly used in cosmetics, toothpaste, chemical processing, etc. Powdered activated carbon has the size from 0.2mm to 0.5 mm should be easily washed away , so they are often used as an adjunct in alum water treatment systems, RO membranes.
Activated carbon powder
Granular activated carbon
Granular activated carbon has the size from 0.2-5mm and the shape is random and heterogeneous. This type is very hard and durable than powder form , as well as more difficult to wash off, suitable for water treatment in daily life, industrial wastewater.
Granular activated carbon
Activated carbon sheet
Activated carbon sheet is the perfect combination of sponges that have been powdered activated carbon with a shaped frame for use inair purification, you often find them in air purifiers or air conditioners.

Mechanism of action of activated carbon
With a structure with many small holes and cracks, activated carbon will be able to easily absorb dirt, impurities and pollutants in water and air such as: Chlorine, benzene, SO2, CO2, H2S, fine dust ,… Accordingly, these pollutants will stick to the surface of the activated carbon, the larger the contact surface, the higher the filtration efficiency.
Mechanism of action of activated carbon
What does activated charcoal do?
Use filtered water to drink
Among the effects of activated carbon, used to treat drinking water is the most widely used, whereby activated carbon will be able to remove heavy metals, fluoride, scum, impurities and other substances. chemicals, organic matter, etc. to make the water cleaner and fresher before drinking.
Use filtered water to drink
Use detoxification in medicine
For health, activated charcoal has the effect of treating diseases such as: fullness, diarrhea, stomach pain, detoxification, … thanks to its properties of absorbing toxins in the body and excreting it. outside.
In particular, activated carbon is used a lot in gas masks to help protect the respiratory system.
Use activated charcoal to whiten teeth
One effect of activated charcoal that is applied by many people is teeth whitening with activated charcoal powder. Thanks to the carbon content, activated charcoal has the effect of whitening teeth by gentle abrasion, without affecting tooth enamel.
Use activated charcoal to whiten teeth
Used to lower blood cholesterol
Thanks to its cholesterol-binding properties and cholesterol-containing bile acids in the intestines, activated charcoal can effectively prevent cholesterol absorption.
Through research, when using 24g of activated charcoal per day, maintained for 4 weeks will contribute to a 25% reduction in cholesterol, an 8% decrease in HDL, and a 25% reduction in LDL.
Used in exhaust gas treatment, deodorization
Activated carbon of all kinds is often used in kitchen deodorizers, air purifiers, air conditioners, … to treat odors, kill bacteria, and waste water in a fresh, safe way for health. .
Used in exhaust gas treatment, deodorization
Used in industry
In metal processing steps, activated carbon is often used in the final step, especially in refining electroplating solutions. On the other hand, activated carbon is also used in the mining industry of gold, silver and precious metals.
Some other apps
