摘要

Indication: Emergency treatment of acute poisoning after ingestion of a large amount of toxin or drug. Activated charcoal--also known as active carbon, activated carbon, adsorbent charcoal, medicinal charcoal, or carbo medidnalis--is a carbon residuederived from vegetable material (e.g., wood pulp). It is produced by exposing the original material to an oxidizing gas compound of steam, oxygen, and acids at high temperatures (900deg C).This activation process creates a network of fine pores (10 to 20nm in size) in the resulting charcoal. The result is a highly porous material with an enormous surface area relative to its weight. The adsorptive capacity of activated charcoal is a function of its binding surface area. In commercial products, the surface area varies from 1000 to 2000 m~2 per gram.
