Activated Carbon

Whatsapp Order

Activated carbon is a highly porous, adsorptive material processed to have an exceptionally large surface area (typically 500-1500 m²/g) through thermal or chemical activation of carbon-rich source materials. This versatile adsorbent exists in powdered (PAC), granular (GAC), pelletized, and extruded forms, with pore structures specifically engineered for different applications ranging from water purification to gas treatment. Its extended surface area and complex pore network (micropores <2nm, mesopores 2-50nm, macropores >50nm) enable superior physical adsorption of contaminants through van der Waals forces, as well as chemical interactions with surface functional groups.
