Description
An inert, amorphous, black powder of Carbon. Activated carbon has tiny particles with very high surface areas due to their fine, honeycomb pore structure. Activated carbon is obtained by the carbonizing of coal, peach pits, hardwood, animal bones, coconuts, and other carbonaceous material. It is activated by heating to a high temperature (800-900 C) with steam or Carbon dioxide to produce its rigid, sponge-like internal structure. The void spaces, which may occupy up to 75% of its volume, provide sites for molecular adsorption. Activated carbon is primarily used as an adsorbent to remove pollutants and other impurities in both gases and liquids. Activated carbon is available in the form of pellets, powder, or fabric. Commercial uses of the sorbent include gas masks, filter systems, decolorizing sugar, solvent recovery, and purification of water and air.
