Carbon, Activated

Name:
Carbon, Activated
Detailed information:
(active carbon; activated charcoal). An amorphous form of carbon characterized by high adsorptivity for many gases, vapors, and colloidal solids. The carbon is obtained by the destructive distillation of wood, nutshells, animal bones, or other carbonaceous material. It is “activated” by heating to 800–900C with steam or carbon dioxide, which results in a porous internal structure (honeycomb-like). The internal surface area of activated carbon averages approximately 10,000 square feet per gram. The density is from 0.08 to 0.5. It is not effective in removing ethylene.

Grade:

Technical, USP, as activated charcoal.

Hazard:

Flammable. Toxic by inhalation of dust.

Use:

Decolorizing of sugar, water and air purification, solvent recovery, waste treatment, removal of sulfur dioxide from stack gases and “clean” rooms, deodorant, removal of jet fumes fromairports, catalyst for natural-gas purification, brewing, chromium electroplating, air- conditioning.
