Activated carbon, is black powder or block, granular, honeycomb amorphous carbon, but also arranged neatly crystalline carbon.In addition to carbon elements, activated carbon also contains two kinds of admixtures: one is chemical binding elements, mainly oxygen and hydrogen, these elements are due to incomplete carbonization and remain in the carbon, or in the activation process, foreign non-carbon elements and activated carbon surface chemical combination;Another kind of admixture is ash, it is the inorganic part of activated carbon, ash in activated carbon is easy to cause secondary pollution.Activated carbon is widely used in production and life because of its strong adsorbability.

Activated carbon according to its different materials can be divided into: coconut shell carbon, shell carbon, wood carbon, coal carbon;According to its shape can be divided into: powder, granular, spherical, columnar and other shapes.Activated carbon can be used in different fields according...
