Why does activated carbon need to be impregnated with potassium permanganate KMnO4?
Conventional activated carbon primarily relies on physical adsorption (using its pore structure to absorb gases or organic matter).
However, for some gases that are low in concentration, difficult to adsorb, or easily permeable (such as formaldehyde, hydrogen sulfide, ammonia, and carbon monoxide), physical adsorption alone is limited in effectiveness.
Potassium permanganate is a strong oxidant. Loading it onto activated carbon imparts both chemical adsorption and oxidative decomposition capabilities.
- The porous structure of activated carbon provides a large surface area for gas adsorption;
- KMnO₄ provides chemical reaction sites, oxidizing and decomposing pollutant molecules into harmless or less harmful substances, such as carbon dioxide and water.
These two effects synergistically significantly increase adsorption capacity and purification efficiency.
How to Impregnate Activated Carbon with Potassium Permanganate KMnO4
The production process of potassium permanganate-impregnated activated carbon involves more than simple physical mixing. Instead, it involves a specific process to uniformly load the potassium permanganate (KMnO₄) solution onto the activated carbon’s developed pore structure and large surface area. The key steps are as follows:
1. Raw Material Selection and Pretreatment
Select high-quality activated carbon (commonly coal-based or coconut shell charcoal) with a high specific surface area and a well-developed micro- and mesoporous structure as the carrier.
Pre-treat the activated carbon, such as washing and drying, to ensure its pores are unobstructed and free of impurities.
2. Preparation of the Impregnation Solution
Dissolve a certain amount of potassium permanganate crystals in deionized water to create a solution of a specific concentration. Controlling the concentration is crucial, as it directly affects the potassium permanganate loading and performance of the final product.
3. Impregnation Process
Mix potassium permanganate (KMnO4) with water at 80-100°C and evenly spray the potassium permanganate solution on the activated carbon. High temperature can accelerate molecular motion and make the impregnation more stable.
4. Drying and Curing
The saturated activated carbon is filtered out and dried at a strictly controlled temperature (typically 80-120°C). The temperature should not be too high to prevent the potassium permanganate from decomposing.
The drying process not only removes moisture but also solidifies the potassium permanganate within the pores of the activated carbon, forming a stable loading structure.
5. Packaging
The dried product must be immediately sealed and packaged in a light-proof and moisture-proof manner, as both the potassium permanganate and the product itself are sensitive to moisture and light.

Activated Carbon Impregnated with Potassium Permanganate KMnO4 Features
This material combines the physical adsorption of activated carbon with the chemical redox ability of potassium permanganate, creating a synergistic effect of “1+1 > 2.”
1. Synergistic Purification Mechanism
- Physical Adsorption: Activated carbon, with its large surface area, efficiently adsorbs volatile organic compounds (VOCs) and odor molecules (such as hydrogen sulfide and ammonia) from the air.
- Chemical Oxidation: Loaded potassium permanganate is a strong oxidant. When adsorbed pollutants (especially reducing gases) come into contact with potassium permanganate, a redox reaction occurs. For example, it oxidizes ethylene (C₂H₄) into carbon dioxide and water, reduces ozone (O₃) into oxygen, and itself is reduced to manganese dioxide (MnO₂). Pollutants are chemically decomposed and will not be released again, thus avoiding secondary pollution.
2. Efficient Removal of Specific Pollutants
- It has extremely high ozone removal efficiency, making it the core material for professional ozone removal filters.
- It can effectively decompose ethylene, which is crucial for preserving the freshness of fruits and vegetables. It has excellent removal performance for a variety of volatile organic compounds, especially aldehydes (such as formaldehyde), sulfides (such as hydrogen sulfide), and nitrogen compounds.
3. Broad-spectrum and targeted removal
It retains the broad-spectrum adsorption capabilities of activated carbon while also enhancing its ability to remove small molecules and highly polar gases that are difficult for activated carbon to adsorb or tend to desorb rapidly.
4. Service life
Advantages: For the treatment of chemical pollutants, the consumption mode of its chemical reaction makes it possible to have a longer lifespan than activated carbon with simple physical adsorption when treating specific gases, and it is not easy to desorb due to changes in ambient temperature and air pressure.
Challenges: Potassium permanganate, as a reactant, is consumed. Once depleted, the material’s chemical oxidation capacity disappears, leaving only the physical adsorption function of the activated carbon. Therefore, its overall lifespan depends on the potassium permanganate loading and the pollutant concentration.
Activated Carbon Potassium Permanganate KMnO4 Applications
Activated carbon impregnated with potassium permanganate KMnO4 has a wide range of irreplaceable applications in various fields:
Air Purification
Industrial and Specialty Gas Treatment
Environmental Protection and Monitoring
Fruit and Vegetable Preservation
1. Air Purification
- Home/Commercial Air Purifiers: Serves as the core filter layer to remove ozone, formaldehyde, VOCs, and odors, particularly in newly renovated areas, industrial areas, or areas with heavy traffic.
- Fresh Air Systems: Installed in supply or return air ducts, purifies incoming outdoor air (especially air containing ozone) or recirculated indoor air.
2. Industrial and Specialty Gas Treatment
- Ozone Removal: Treats exhaust gases in factories using ozone for sterilization, bleaching, or water treatment, protecting the environment and personnel. It is also used to decompose ozone generated by office copiers and laser printers.
- Chemical and Spray Painting Industries: Treats specific waste gases generated during production processes, such as sulfides and nitrogen oxides.
3. Fruit and Vegetable Preservation
This is a very important application area. Fruits and vegetables release ethylene during ripening. Ethylene is a ripening hormone that accelerates ripening and spoilage.
Activated carbon impregnated with potassium permanganate can effectively decompose ethylene, significantly extending the shelf life of fruits and vegetables. It is commonly used in cold storage, refrigerated transport boxes, and supermarket fresh-keeping packaging.
4. Environmental Protection and Monitoring
- Used in environmental monitoring stations as a pretreatment before sampling to remove interfering gases.
- Used for deodorization in sewage treatment plants, garbage stations, and other locations.
5. Military and Protection
Used in the manufacture of gas masks or canisters in collective protection systems to protect against chemical warfare agents and toxic industrial chemicals.
In summary, activated carbon impregnated with potassium permanganate is a functional material that achieves efficient and deep purification through the synergistic effects of chemistry and physics. It is particularly adept at addressing difficult problems that cannot be addressed by simple physical adsorption, such as ozone, ethylene, and some small polar molecules. It plays a key role in air purification, industrial safety, and fruit and vegetable preservation.
