Activated Carbon is an excellent adsorbent used for purifying air, water, and gas and controlling odour. It has small and low-volume pores to increase the surface area for chemical reactions or adsorption. The Carbon made from coconut shells is also used in food production and industrial processes. It is also used in various health, safety, and environmental applications.

It is a low-cost material with distinct properties like high specific surface area, high porosity, and desired surface functionalization. Because of that, activated Carbon is diversely used for practical applications in adsorption, removal of pollutants, water treatment, and energy.
