Activated carbon adsorption is a proven air and water purification technology that has been used in various applications for decades. This technology uses activated carbon's high adsorption ability to remove a wide range of pollutants from air and water.

Activated carbon is a porous material made from organic materials such as coconut shells or wood and is activated through a process of thermal charring at high temperatures. Activation creates thousands of tiny pores in the carbon grain, providing very large surface areas on which pollutants can be bound.

Adsorption is a process in which molecules of a liquid or gas stick to a solid surface. This happens due to the attraction between the particles of the liquid or gas and the surface. It is important to note that adsorption should not be confused with absorption, where particles actually penetrate a material.

Adsorption occurs in many different applications, such as air purification, water treatment, separation of gases and removal of pollutants from wastewater. It is also used in the pharmaceutical and food industries to remove impurities or to isolate specific components.

adsorption

The principle of adsorption is based on the fact that solid surfaces usually have countless pores that can absorb particles. The larger the surface and the larger the pores, the more particles can be adsorbed. The ability of a solid surface to adsorb particles is called adsorption capacity.

Adsorption can also be influenced by various factors such as temperature, pressure, chemical composition and electrical charge. It is important to consider these factors when selecting a suitable adsorption material to ensure effective adsorption.

Air purification

In air purification, activated carbon is used in the filters of air purification systems to remove a variety of pollutants including cigarette smoke, particulate matter, pet odors, allergens and toxic gases. By adsorbing these pollutants on the surface of the activated carbon, air quality is improved and health is protected.

Water treatment

Activated carbon is used in water treatment to remove chlorine, heavy metals, pesticides, drug residues and other contaminants from drinking water. This is particularly important because these contaminants are often harmful to human health and can affect the taste and appearance of water.

It is important to note that activated carbon cannot be used indefinitely and must be replaced regularly to maintain its effectiveness.

In summary, adsorption is a process in which particles of a liquid or gas stick to a solid surface, which is caused by the attractive force between the particles and the surface. It is a proven technology used in many applications to remove contaminants or isolate specific components.
