aktívszén

Aktivszén, also known as activated charcoal, is a porous black powder or granular form of carbon. It is produced by heating carbon-rich materials like wood, peat, or coconut shells in the absence of air, a process called carbonization. This is followed by activation, which involves exposing the carbonized material to oxidizing agents at high temperatures. This activation process increases the surface area and pore volume of the carbon, making it highly effective at adsorbing substances.

The primary characteristic of aktivszén is its immense internal surface area. A single gram can have a surface area equivalent to a football field. This vast surface allows it to trap and hold a wide variety of molecules through a process called adsorption, where substances adhere to its surface rather than being absorbed into it.

Aktivszén has numerous applications due to its adsorptive properties. It is widely used in water and air purification systems to remove impurities, odors, and colors. In the medical field, it is administered orally to treat certain types of poisoning and drug overdoses, as it binds to toxins in the digestive tract and prevents their absorption into the bloodstream. It is also found in some over-the-counter products for gas relief and teeth whitening. Its industrial uses include solvent recovery, catalyst support, and in the production of various chemical compounds.
