Allotropes are the existence of an element in more than one form. Carbon is one of the elements that contain many allotropes. Each allotrope of carbon has its own different properties. The allotropes of carbon are diamond‚ graphite‚ fullerenes‚ carbon nanotubes‚ carbon nanobuds‚ amorphous carbon‚ glassy carbon‚ lonsdaleite‚ and carbon nanofoam. Diamond is the best know allotrope of carbon. It is the hardest known natural mineral which makes it very rough. In the structure of the diamond‚ each carbon

Activated Carbon Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface
