The activated carbon adsorption method is a method with wide application, mature technology and many kinds of adsorbed substances. As an excellent physical and chemical adsorption material, active carbon has attracted more and more attention. Activated charcoal can absorb all harmful gas molecules such as formaldehyde, ammonia, benzene, xylene, radon, etc. in the indoor air, quickly eliminate decoration odors, and evenly adjust the humidity of the space. It is suitable for rooms, furniture closets, bookcases, shoe cabinets, shoe cabinets, shoe cabinets , Shoe cabinets, refrigerators, toilets, floors, fish tanks, cars, air conditioners, computers, offices, hotels, entertainment and other places have very good effects. It is the nemesis of formaldehyde and anti-virus. Activated carbon is also called “multifunctional adsorbent”. What is its principle?

The activated carbon adsorption method uses porous activated carbon to adsorb one or more substances in the water to the surface of the activated carbon, taking dissolved organic matter as the removal target, synthesizing detergents, microorganisms, viruses and a certain amount of heavy metals, and can decolor them, Deodorize and purify the air. In water treatment, activated carbon, sulfonated coal, zeolite, coke, etc. are all commonly used adsorbents. The activated carbon’s activated carbon lattice forms well-developed pores of various shapes and sizes, and the specific surface area is significantly increased. Enhanced.

Activated carbon is a very fine carbon particle with a large surface area, and there are even smaller pores in the capillary of the carbon particle. This kind of capillary has a strong adsorption capacity, and due to the large surface area of ​​carbon particles, it can fully contact with gas (impurities). When these gases (impurities) encounter the capillary and are adsorbed, they play a role in purification. The surface area of ​​activated carbon is very important. Only the BET method can detect the specific surface area of ​​activated carbon, and many instruments can only do direct comparison methods. Specific surface area inspection is actually a work that takes time. Depending on the adsorption capacity of the sample, the inspection of some samples may take a whole day. If the inspection process is not fully automated, the inspector cannot leave at any time and is highly concentrated. Observe the dashboard and operate the knob.
