Hot sale activated carbon
Activated carbon (also called active carbon, 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 and chemical reactions. It is usually derived from charcoal. Activated carbon is valuable for a variety of applications. Examples include gas purification, water purification, metal extraction, gold recovery, medicine, sewage treatment, air filters in gas masks and filter masks, and filters in compressed air. In addition, activated carbon is useful for the deodorization of closed spaces such as refrigerators and warehouses. Sufficient activation for useful applications may come solely from the high surface area, though further chemical treatment often enhances the adsorption ability of the material.
