The history of activated carbon
Origin and first uses
Activated carbon, known since ancient times, has been used for various medicinal and purification applications. The Egyptians used it around 1550 BC. BC to purify water, while Hippocrates, around 400 BC. BC, already recognized its medicinal abilities 1. This tradition has continued over the centuries, where charcoal, in its most natural form, was frequently used as a pigment for cave paintings and as a means of purifying water and air 2.
Evolution of the production process
In the 18th century, charcoal began to be used in a more structured way with animal black, a product derived from bones, used for filtration and decolorization of liquids like sugar 1. However, it was in the 1900th century that production techniques were significantly improved. Physical or chemical treatment processes were developed, notably by the Swedish chemist von Ostreijko who defined the bases of the physical and chemical activation of coal in 1901 and XNUMX 1. These innovations enabled diversified industrial production, increasing the efficiency of activated carbon.
Modern uses
With the advent of the industrial era, the use of activated carbon diversified. It has found its place in the filtration of water and gases, thanks to its porosity which allows unwanted molecules to be captured, thus improving the quality of drinking water and controlling air pollution. 2. In addition, activated charcoal has become an essential tool in pharmacy for the treatment of poisoning and overdose, effectively absorbing toxins in the stomach 2. Its ability to adsorb a variety of molecules has also led to its increasing use in capsule form for digestive well-being and body detoxification. 2.
Activated carbon manufacturing process
Selection of raw materials
Activated carbon is produced from various carbon-rich sources, such as mineral coals (anthracite, lignite, bituminous) and woody plant materials such as wood and coconut shells. These raw materials are selected for their high content of cellulosic fibers, essential to obtain an effective porous structure 3.
Carbonization
The first crucial step in the manufacture of activated carbon is carbonization. This step involves the thermolysis of raw materials at low temperatures, where volatile components are removed. This process leads to the formation of an initial carbon with a cavernous structure, thus preparing the material for subsequent activation 3.
Activation
Activation is the second key step and can be achieved by two main methods: chemical activation and steam activation. Chemical activation involves the impregnation of the carbon with dehydrating agents such as phosphoric acid, followed by calcination at temperatures between 500 and 800°C. On the other hand, steam activation is done at higher temperatures (800-1100°C) and uses steam to trigger reactions that increase the porosity of the coal 3.
Packaging and shapes available
Once activated, activated carbon is packaged in different forms depending on its intended use. The most common forms include powdered carbon (PAC), used for clarification of liquids, and granular carbon (GAC), which serves as a filter bed for water. These shapes differ in their particular dimensions and their specific applications, thus allowing optimized use according to purification needs. 4.
Differences between activated charcoal and activated vegetable charcoal
Origin and manufacturing process
Activated carbon can be produced from a variety of organic materials, including wood and even petroleum residues, while activated vegetable carbon comes exclusively from carbonized plant materials, such as wood or coconut husks. The process of manufacturing activated vegetable charcoal involves a carbonization step followed by activation by steam at high temperature, which is specific to this type of charcoal. 5.
Structure and adsorption capacity
The porous structure of activated vegetable carbon is more developed than that of activated carbon, giving it a larger adsorption surface. This improved structure allows activated vegetable charcoal to capture and retain unwanted molecules more effectively. Researchers have estimated that a single gram of powdered activated charcoal has an adsorption surface area of up to 2500 m², which is equivalent to approximately 15 volleyball courts. 6.
Applications and uses
The applications of activated carbon and activated vegetable carbon differ significantly depending on their properties. Activated carbon is frequently used in air and water filters due to its ability to improve water and air quality. On the other hand, due to its health and skin benefits, activated charcoal is used more in dietary supplements and skin care products. 5.
Adsorption properties of activated carbon
Adsorption mechanism
Activated carbon adsorption is characterized by its ability to remove soluble substances from water, making it a predominant choice for the treatment of various contaminants. This process involves the transfer of adsorbate, a substance to be removed, to activated carbon which acts as an adsorbent. Activated carbon, with an internal surface area of up to between 500 and 1500 m²/g, provides a large surface area for adsorption, thereby optimizing the removal of compounds such as phenols, saturated hydrocarbons, pesticides, and heavy metals 7.
Adsorption takes place in four main stages: the rapid transfer of the particle to the carbon, the displacement of the bound water, the slow diffusion inside the carbon under the influence of the concentration gradient, and finally the rapid adsorption in a micropore 7. Factors influencing adsorption efficiency include substance concentration, temperature, and substance polarity, with less effectiveness against polar solvents and low molecular charge chlorinated compounds. 7.
Ability to capture toxins and impurities
Activated carbon is particularly effective at capturing toxins and impurities thanks to its unique porous structure. The pores of carbon, measuring 1 to 2 nm for gases and up to 10 nm for liquids, allow efficient adsorption of different substances 1. This porosity is influenced by the original material; for example, coconut shells produce micropores while wood produces meso/macropores 1.
Interactions between the molecules and the surface of the activated carbon, including van der Waals forces and hydrogen bonds, facilitate the attachment of the molecules to the adsorbent. Additionally, the presence of calcium ions can improve the adsorption of some anionic organic micropollutants, although this method is not always economically viable 1 1.
In summary, activated carbon uses its immense internal surface area and adsorption capacity to effectively purify water and air, removing a wide range of contaminants and thereby improving environmental quality and public health.
Health Benefits of Activated Charcoal
Improved digestion
Activated charcoal plays a crucial role in improving digestion by adsorbing toxins and pathogens present in the intestine, making them easier to eliminate from the body. This purification action contributes to a natural “cleansing” of the digestive system, helping to regulate intestinal transit and reducing the risk of various digestive disorders. 8. By capturing excess gas, activated charcoal also limits feelings of heaviness and discomfort after meals, providing notable relief for people suffering from chronic flatulence. 8.
Reduction of bloating
Activated charcoal is effective in reducing bloating and intestinal gas, thanks to its ability to bind to acids that cause indigestion. By absorbing these substances, it helps reduce the formation of gas during the fermentation of food in the digestive tract, which results in a less bloated stomach and an improved feeling of lightness 9. This property is particularly beneficial for individuals suffering from irritable bowel syndrome or other similar digestive disorders. 9.
General detoxification
Activated charcoal contributes to general detoxification of the body by trapping unwanted substances such as heavy metals, pesticide residues and other toxins, which are then eliminated naturally through the stools 10. This adsorption capacity also extends to reducing bad breath and combating excess fats in the blood, which supports the optimal functioning of internal organs and promotes improved overall health. 10. Additionally, activated charcoal helps eliminate toxins not only from the digestive system but also from blood plasma, providing purification that benefits the entire body 11.
Cosmetic use of activated carbon
