Wood Activated Carbon is a black powder, granular or pellet or amorphous with porous
Carbon. The main component is carbon, which also contains small amounts of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It is mainly made of wood, fruit shells, coal and other high-temperature activation. Carbon is the most stable element in nature.
Activated Carbon also has this feature. Activated carbon pore structure is advanced, with a large surface area (500 ~ 1000 m2/g), even higher, has a strong physical adsorption properties, can adsorb gas, liquid or colloidal solids; for gases, liquids, adsorbed substances The quality can be close to the quality of the activated carbon itself. Its adsorption is selective, non-polar substances are more easily adsorbed than polar substances. In the same series of substances, substances with higher boiling points are more easily adsorbed, and the pressure is higher, the temperature is lower, the concentration is greater, and the amount of adsorption is greater. Conversely, decompression and warming are favorable for desorption of gases.
