Impregnated activated carbon is made of activated carbon with high adsorption performance as raw material, impregnated with potassium hydroxide, sodium hydroxide, hydrogen peroxide and other solutions, and then refined by burning and drying at 130°-180°.
Highly selective adsorption: By selecting the right impregnant, activated carbon can more effectively adsorb specific pollutants such as metal ions, acidic gases or organic compounds.
Enhanced chemical reactivity: Some impregnated activated carbon can also promote chemical reactions, thereby degrading adsorbed pollutants. For example, activated carbon impregnated with alkali metal compounds can catalyze oxidation and decompose certain oxides.
Adaptable to a variety of media: Impregnated activated carbon can be used for gas phase and liquid phase adsorption, greatly expanding its application range.
Air purification: Activated carbon impregnated with chemicals such as sodium hydroxide, potassium iodide or palladium is used to remove acidic gases (such as hydrogen sulfide, chlorine) and organic volatiles (such as mercury vapor, formaldehyde) in the air.
Water treatment: Activated carbon impregnated with copper or iron is used to remove cyanide and sulfide from water, which is very effective for the treatment of some industrial wastewater.
Protective equipment: In industrial and military protection, activated carbon impregnated with activated chemicals is used in gas masks and other protective equipment to remove harmful gases and vapors.
Heavy metal removal: Activated carbon with sulfide or other organic complexing agents is used to remove heavy metals such as lead and chromium from sewage.
In summary, the effectiveness of impregnated activated carbon depends on choosing the right impregnant and treatment method to achieve the best adsorption and removal effect for specific pollutants. Its flexibility and versatility make it an important tool in the field of pollution control.
