Why can activated carbon fiber filters remove chlorine, organic pollutants, odors and smells from water?

Activated carbon fiber filters can remove chlorine, organic pollutants, odors and smells from water, mainly due to its special material and structural characteristics. The following is a specific analysis of the reasons:
Adsorption capacity: The specific surface area of ​​activated carbon fiber is extremely large, mainly due to the extremely small pore structure on its surface. These pore structures include micropores, mesopores and macropores, which together constitute a complex network of activated carbon fibers. These pore structures provide activated carbon fibers with a huge adsorption area, allowing it to effectively adsorb and capture pollutant molecules in gas or liquid. When water flows through the activated carbon fiber filter, the pollutant molecules are adsorbed to the surface of these pores and removed. This strong adsorption capacity is the key to the activated carbon fiber filter to remove impurities in water.
Removal of chlorine: Chlorine in water usually exists in the form of chloride ions or hypochlorous acid, which have a certain pungent odor and have potential effects on human health. The microporous structure of activated carbon fiber can selectively adsorb these chlorine molecules and their related compounds. When water molecules flow through the activated carbon fiber, chlorine molecules are adsorbed to the pore surface. In addition, activated carbon fiber can also catalyze the reaction of chlorine molecules with water vapor to form harmless chloride ions and oxygen (or hydrogen), thereby further removing chlorine from the water. This catalytic reaction reduces the chlorine content in the water and improves the taste and odor of the water.
Removal of organic pollutants: There are many types of organic pollutants in water, including pesticides, petroleum products, solvents and dyes. These pollutants often have complex molecular structures and potential hazards. The strong adsorption of activated carbon fiber enables it to adsorb these organic pollutants to the surface. When water flows through the filter, organic pollutants in the water collide with the surface of the activated carbon fiber and are adsorbed. These pollutant molecules are fixed in the pores of the activated carbon fiber and are removed. This adsorption is of great significance to improving water quality and can significantly reduce the content of organic pollutants in water.
Removal of odor and smell: Odor and smell in water usually come from volatile organic compounds and other odor substances. These substances have a low boiling point and are easily volatilized into the air and produce unpleasant odors. Activated carbon fiber has a strong adsorption capacity for VOCs and other odor substances. When water flows through the filter, these odor substances are adsorbed into the pores of the activated carbon fiber. The complex pore structure of the activated carbon fiber can accommodate a large number of odor molecules and firmly fix them. In this way, the activated carbon fiber filter can significantly reduce or eliminate the odor in the water and improve the sensory quality of the water.
In summary, the activated carbon fiber filter can effectively remove chlorine, organic pollutants, odors and smells in the water with its unique material and structural characteristics, especially the high specific surface area and strong adsorption capacity, to provide clean and safe drinking water.
