活性炭的吸附：
活性炭的吸附可分为物理吸附和化学吸附。
物理吸附：
主要发生在活性炭去除液相和气相中杂质的过程中。活性炭的多孔结构提供了大量的表面积，从而使其非常容易达到吸收收集 杂质的目的。就象磁力一样，所有的分子之间都具有相互引力。正因为如此，活性炭孔壁上的大量的分子可以产生强大的引力，从 而达到将介质中的杂质吸引到孔径中的目的。必须指出的是，这些被吸附的杂质的分子直径必须是要小于活性炭的孔径，这样才可能保证杂质被吸收到孔径中。这也就是 为什么我们通过不断地改变原材料和活化条件来创造具有不同的孔径结构的活性炭，从而适用于各种杂质吸收的应用。
化学吸附：
除了物理吸附之外，化学反应也经常发生在活性炭的表面。活性炭不仅含碳，而且在其表面含有少量的化学结合、功能团形式的氧和氢，例如羧基、羟基、酚类、内脂类、醌类、醚类等。 这些表面上含有地氧化物或络合物可以与被吸附的物质发生化学反应，从而与被吸附物质结合聚集到活性炭的表面。活性炭的吸附正是上述二种吸附综合作用的结果。
ADSORPTION OF ACTIVATED CARBON: Adsorption of activated carbon can be divided into physical adsorption and chemical adsorption. Physical adsorption: mainly occurs in the active carbon removal of impurities in the liquid and gas phase of the process. The porous structure of activated carbon provides a large surface area, which makes it very easy to absorb and collect impurities. Just like magnetism, all the molecules are attracted to each other. Because of this, a large number of molecules on the Pore Wall of activated carbon can exert a strong gravitational force, thereby attracting impurities in the medium to the pore size. It is important to note that the molecular diameter of these adsorbed impurities must be smaller than the pore diameter of activated carbon, so that it is possible to ensure that the impurities are absorbed into the pore diameter. This is why we are constantly changing the raw materials and activation conditions to create activated carbons with different Pore structure, thus suitable for various impurity absorption applications. CHEMISORPTION: In addition to physical adsorption, chemical reactions often occur on the surface of activated carbon. Activated Carbon not only contains carbon, but also a small amount of chemical binding, functional group form of oxygen and hydrogen on its surface, such as Carboxyl, hydroxyl, phenol, lipid, quinone, ether, etc. . These surfaces contain ground oxides or complexes that react with the adsorbed material to bind and aggregate to the surface of the activated carbon. The adsorption of activated carbon is the result of the above two kinds of adsorption.
