Impregnated activated carbon

Impregnated activated carbon is selected from high quality activated carbon with high adsorption performance, impregnated with silver, copper oxide, phosphoric acid, KOH, NaOH and so on, and then refined by 130°-180° cremation. Impregnated activated carbon is widely used to sterilizationin the water and remove organic gases and vapors from air or other gas streams, such as hydrogen sulfide, H2S, HCN, phosphine and arsine, etc.

Impregnated activated carbon is used for the adsorption of gases and vapours that are adsorbed by standard activated carbon very little or are not adsorbed at all. These are low-molecular and polar substances with a low concentration and toxic effects. The complex chemical reaction of a harmful substance with an impregnating agent brings about the removal of the substance from the air – harmful gases are chemically bonded to the impregnating agent in activated carbon (chemical adsorption).


The following is the parameter information of the impregnated activated carbon we mainly produce. We can also customize different impregnated agents to the special application.
