Activated carbon is a readily available material that can be added to fertilizers or manures to reduce nitrate nitrogen (NO3-N) contamination of surface and near-surface groundwater. Although purifying gold had been done for centuries, beginning in the back half of the 20th century activated carbon began to be used to purify gold because of its strong adsorption capabilities. 1 Grupo de Investigación en Sólidos Porosos y Calorimetría, Departamento de Química, Facultad de Ciencias, Universidad de los Andes, Carrera 1 No. Adsorption of gold complexes (especially ion disianoaurat) on activated carbon is the basis of modern techniques for gold extraction process.

The term 'activated' refers to the way the carbon has been prepared to enhance its ability to physically 'adsorb' chemicals to its surface. What can be removed and what can't? Our experimental results showed that the size of activated carbon had little effect on the adsorption of little molecular substance, but it had significant effect on the adsorption of middle molecular substance. Activated carbon, also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions.

Activated carbon is a form of carbon usually derived from charcoal.
