Description

Description générale

Activated charcoal can be used for the following:

• Fiber coating to compare solid-phase microextraction efficiency of the multiwalled carbon nanotubes in water and milk samples before GC-ECD analysis.[1]
• It may be used to study its effect on tissue cultures of Daucus carota, Happlopapus gracilis and Allum cepa var. proliferum, to check the adsorption of metabolites inhibiting morphognesis.[2]
• It may also be used in the plant tissue culture to increase the adsorption of auxin and cytokinin from the culture media.[3]
• It may also be used as the primary gastrointestinal decontamination procedure after acute drug overdose.[4]
• It may also be used for the adsorption of dyes namely malachite green, bromophenol blue, alizarine red-S, methylene blue, eriochrome black-T, phenol red, methyl blue, and methyl violet from aqueous media.[5]
• Oral activated charcoal may be also used for adsorption of theophylline, hence can be effectively used in patients with theophylline poisoning.[6]

Activated charcoal or activated carbon is an adsorbent used to remove broad spectrum of pollutants in air, water and soil, and is non-toxic in nature.[7][8] It is odourless and tasteless and can be prepared from any carbonaceous material using gas or chemical activation methods. Gas activation is preferred when the raw material has less than 25% moisture content.[8]
