Why is activated carbon considered the best adsorbent in nature? Activated carbon – the best adsorbent in nature – is an amorphous carbon in the form of black powder or particles, featuring a large specific surface area and the ability to undergo electrostatic adsorption. Activated carbon is used as a filter element in water purifiers, capable of filtering out harmful substances in water; it is particularly effective at removing residual chlorine and unpleasant odors, as well as organic pollutants that are harmful to the human body. Currently, water treatment plants in pilot cities such as Shanghai are also starting to use powdered activated carbon dosing systems to supply cleaner and healthier water to the general public. Activated carbon rods with strong adsorption capacity: Among various types of activated carbon, granular and powdered activated carbon are the most common. They can adsorb impurities in water, are inexpensive, and are widely used. However, the structure of granular and powdered activated carbon is not tight enough, and the adsorption is incomplete, which very likely results in some unfiltered water flowing out through the gaps in the filter material. High-quality water purifiers using activated carbon rods as filter elements are already available on the market. Activated carbon rods have a high density and strong adsorption capacity. The adsorption surface area of certain high-performance black miracle sintered activated carbon rods is quite substantial: the surface area obtained by expanding 1 gram of activated carbon powder is equivalent to that of a standard football field. Moreover, specially treated activated carbon rods can be made into a structure that is loose on the outside and tight on the inside, enabling physical filtration to block impurities such as rust, sediment, and spore capsules. Even more astonishing is the power of the combination of activated carbon and other technologies. For example, some food-grade polymer materials can be added to activated carbon rods, which enables the filtration of heavy metals such as lead from water as well as the prevention of scale formation ； In higher-end water purifiers, the filter elements combine activated carbon rods with high-strength filter membranes of medical grade, thereby significantly improving the filtering performance.
