Impregnated activated carbon is activated carbon that is injected into specific solutions, chemicals, or metal, through which the adsorption properties of the activated carbon are significantly enhanced. Activated carbon is a porous material with a large number of micropores and mesopores that provide a large specific surface area, giving it excellent adsorption properties for gases, liquids, and solute molecules. By impregnating activated carbon, the properties of the activated carbon can be altered to give it stable adsorption properties for specific applications.

Activated carbon is impregnated with different impregnating agents, which can be used in different special applications for adsorption of target pollutants or chemicals. Common impregnating agents are KOH, KI, KMnO4, Ag, etc.,

In the impregnation process, the activated carbon is impregnated with special chemicals that allow the activated carbon to come into full contact with the impregnating agent so that it is completely saturated. These impregnating agents can be acids, bases, salts, oxides, etc., such as KOH, NaOH, HNO3, etc., and can be used for specific applications, such as water treatment, air purification, industrial waste gases, and metal recycling. Currently, Huamei Company offers the following products of impregnated activated carbon：

When selecting an activated carbon impregnating agent, it depends on the type of target pollutant to be removed and the desired functionality or enhancement. For different pollutants, using different impregnating agents, activated carbon has a stronger adsorption or chemical reaction ability to the target pollutant, improving treatment efficiency. At the same time, we have to consider the pH value of the medium and choose the impregnating agent that is compatible with the conditions, otherwise it will destroy its acid-base environment.
