Carbon

CAS 7440-44-0

Carbon (CAS 7440-44-0) illustrates how molecular structure determines chemical role. Carbon has CAS 7440-44-0, while the chemBlink name activated carbon refers to highly porous carbonaceous materials engineered for adsorption. Activated carbon is made from carbon-rich feedstocks such as coal, wood, coconut shell, or other biomass by carbonization followed by physical or chemical activation. Activation creates an enormous internal pore network, so performance depends on surface area, pore-size distribution, surface chemistry, and particle form rather than one molecular structure. Activated carbon is important in drinking-water and wastewater treatment, air and gas purification, solvent recovery, food and chemical processing, and medical management of selected poisonings. Different activated carbons are not interchangeable because pore architecture and surface chemistry determine which molecules are adsorbed most effectively.
