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. 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.
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.
- 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.
- It may also be used in the plant tissue culture to increase the adsorption of auxin and cytokinin from the culture media.
- It may also be used as the primary gastrointestinal decontamination procedure after acute drug overdose.
- 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.
- Oral activated charcoal may be also used for adsorption of theophylline, hence can be effectively used in patients with theophylline poisoning.
