Activated carbon (AC) physical and chemical properties
Time of Update: 2022-01-04
Powdered activated carbon has strong adsorption capacity, easy preparation and low price, but it is difficult to regenerate and generally cannot be reused .
(2) Because of its huge accessible inner surface (and huge pore volume), activated carbon can adsorb more non-polar and weakly polar organic molecules than other adsorbents .

Chemical activation and catalytic activation modification of activated carbon fiber
Time of Update: 2021-11-15
Gas-phase oxidation means that ACF is oxidized in the air at a temperature of 300-350℃ to produce oxygen-containing functional groups on the surface to improve hydrophilicity and surface acidity; liquid-phase oxidation is ACF reacts with acidic solutions such as nitric acid and sulfuric acid to introduce oxygen-containing groups.

Activated carbon fiber (ACF) physical and chemical properties
Time of Update: 2021-11-15
Table 4-36 ACF morphological characteristics Activated carbon fiber has a very high specific surface area, and the BET specific surface area is about 1000-2000m 2 /g .
In addition to these characteristics, the practical application of ACF is still limited by its high price .
