Impregnated activated carbon

The surface of ordinary activated carbon is non-polar, since the adsorption force is mainly physical adsorption by van der Waals attraction, it does not have sucient adsorption capacity for components with low boiling point and polarity, such as hydrogen sulfide or ammonia. Therefore, when using impregnated activated carbon with selective adsorption to certain components by chemical modification of the surface of activated carbon or applying chemicals, in addition to physical adsorption due to the large surface area and many micropores of activated carbon, it is resistant to pollution and various chemical reactions. It is cost-eective because the deodorization and removal eect is greatly increased, while the service life of activated carbon is increased.

Impregnated activated carbon is a specialized form of activated carbon that has been treated or infused with certain substances to enhance its adsorption capabilities for specific pollutants. This impregnation process involves incorporating materials such as silver, copper, sulfur, or other compounds into the activated carbon matrix, resulting in unique properties and targeted adsorption performance.

Silver impregnated activated carbon is widely used for its antimicrobial properties. The silver particles embedded within the activated carbon structure inhibit the growth of bacteria and other microorganisms, making it ideal for applications in water treatment, air filtration, and medical settings where microbial control is crucial.

Similarly, copper impregnated activated carbon offers excellent antimicrobial properties. It is effective in reducing the growth of bacteria and preventing biofilm formation. This impregnated carbon is commonly used in water filtration systems, particularly in environments where bacterial contamination is a concern.

Impregnated activated carbon also includes sulfur impregnated activated carbon. The addition of sulfur enhances the carbon’s ability to adsorb specific gases, such as hydrogen sulfide, mercaptans, and other sulfur-containing compounds. This makes it suitable for applications in odor control, gas purification, and industrial processes where sulfur compounds need to be removed.

Impregnated carbon are general terms used to describe activated carbon that has been treated with various substances. These impregnations can provide enhanced performance for specific applications, such as odor removal, gas purification, or specialty filtration.

When selecting impregnated activated carbon, it is essential to consider the specific impregnation agent and its intended application. Our range of impregnated activated carbon products offers reliable solutions for various industries, ensuring effective adsorption and targeted removal of specific pollutants.

Application of impregnated activated carbon to remove harmful gases

Impregnated activated carbon to remove dicult odor gases: L CGA-AB

Ordinary impregnated activated carbon is somewhat deficient in the adsorption capacity of various harmful and odorous gases due to simple treatment with acidic and basic modifiers. The new product combines excellent adsorption and antibacterial ability against various harmful gases such as hydrogen sulfide, hydrogen chloride, ammonia and aldehyde through combined processes such as linear functionalization, complex conversion of eective compounds and post-treatment, thereby improving filtration, performance, extending replacement cycles and creating new products. It is possible to implement multifunctionality and economic feasibility by simplifying processes.

Pollutant adsorption model of new product Compared with existing products, the new product has greatly increased absorption sites capable of reacting with harmful gases, and the adhesion between the eective modifier and the adsorbent is strong and excellent.
