Description:
Activated carbon can be used as a filter for molecular substances. Due to the large number of pores in the activated carbon, as well as the very small pore size (1 to 50 nm), the surface area of these pores adds up to around 10,000 times more than the surface area of normal charcoal. The graphic shows the typical pore sizes and clearly illustrates how the large “internal” surface area of activated carbon is achieved.
The graphic can be labeled individually or as a whole.
