General description

Activated coconut charcoal (activated carbon) is used extensively as a general purpose adsorbent, especially for purification applications where the trapped compounds do not need to be recovered. It is not as widely used for thermal desorption and chromatographic applications due to two major drawbacks; its adsorptive strength may be too strong to allow complete desorption, and it is more suitable for applications that employ chemical desorption instead of thermal desorption. However, there are applications where charcoal is and can be used, such as the adsorption/desorption of the very volatile analytes halocarbon 12 and chloromethane.
