Description

• General description: Activated charcoal or activated carbon is nontoxic in nature[1] and is used as an adsorbent to remove broad spectrum of pollutants in air, water and soil.[2] It does not lose potency when kept in container. It has no odour or taste.[1] It can be prepared from any carboneous material using chemical or gas activation methods. Gas activation is preferred when the raw material has less than 25% moisture content.[2]
• Application: It may be used for fiber coating multiwalled carbon nanotubes to compare its solid-phase microextraction efficiency in water and milk samples before GC-ECD analysis.[3]
