Activated carbon, what is activated carbon,

Activated carbon (also called activated charcoal, activated coal or active carbon) is a very useful adsorbent. Due to their high surface area, pore structure (micro, meso and macro), and high degree of surface reactivity, activated carbon can be used to purify, dechlorinate, deodorize and decolorize both liquid and vapor applications.
