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

Charactor for activated carbon 

1. Low ash
2. High strength
3. Developed pores
4. Easy regeneration
5. Strong adsorption capacity
6. Large specific surface area
