This article will introduce in detail what activated carbon impregnated copper oxide is, its working principle and function.
What is activated carbon impregnated copper oxide?
Activated carbon impregnated copper oxide is a supported adsorption material that evenly distributes copper oxide (CuO) on the pore surface of activated carbon, making it capable of both physical adsorption and chemical reaction. Activated carbon is responsible for adsorbing gas molecules, while copper oxide reacts chemically with certain harmful gases, converting them into harmless solid compounds or gases, thereby achieving efficient purification.Working principle of CuO impregnated activated carbon
The working principle includes two aspects:Physical adsorption:
Activated carbon has a developed pore structure and ultra-high specific surface area (usually 500~1500 m²/g), which can adsorb gas molecules and capture them in the pores.
Chemical reaction:
Copper oxide can react chemically with specific harmful gases (such as hydrogen sulfide, ammonia, sulfur dioxide), converting them into non-toxic and harmless products.
For example: Hydrogen sulfide (H₂S) removal reaction:
H₂S + CuO → CuS + H₂O
The reaction generates stable copper sulfide (CuS), thereby achieving complete removal of hydrogen sulfide.
Ammonia (NH₃) or other corrosive gases can also react with copper oxide to reduce pollution.
Specific application of CuO impregnated activated carbon
Efficient removal of hydrogen sulfide (H₂S)Hydrogen sulfide reacts chemically with copper oxide to generate stable copper sulfide (CuS), thereby completely removing hydrogen sulfide.
Removal of ammonia (NH₃)
Copper oxide can neutralize ammonia to generate harmless substances, which are suitable for chemical waste gas treatment and air purification.
Removal of acidic gases (SO₂, Cl₂)
It has excellent adsorption and reaction properties for harmful acidic gases such as sulfur dioxide and chlorine.
