How much do you know about activated carbon?

Activated Carbon is a non-crystalline porous carbon material that has undergone special treatment. Due to its large specific surface

 area and well-developed microporous structure, it exhibits extremely strong adsorption capacity. It is commonly used in water

 purification,air deodorization (especially for adsorbing formaldehyde and VOCs), decolorization, and industrial refinement. Its main

 raw materials  include coal, wood, coconut shells, etc., and it is produced through carbonization and activation processes.

The core characteristics and functions of activated carbon:

Advanced pore structure: The activation treatment removes impurities, creating a large number of micropores, thereby providing an

 extremely large specific surface area for gas or liquid molecules to attach to.

High adsorption capacity: Widely used in water purifier filter cores, household air purifying carbon bags, refrigerator deodorizers, etc.

Widely applicable in various fields: including environmental protection (wastewater treatment), food (color removal of sugar and wine),

 medicine (anti-toxic masks, medical adsorption), and daily life.

Usage Notes:

 Adsorption saturation:

 Activated carbon merely adsorbs pollutants, not decomposes them. Once the fine pores are filled with substances, they need to be

 exposed to sunlight for activation or replaced.

Functional Limitations: For low-concentration and small-space harmful gases (such as those from newly renovated rooms), activated

 carbon packs combined with ventilation have a good effect, but their effectiveness is limited for severe air pollution.
