活性炭的吸附：
活性炭的吸附可分為物理吸附和化學(xué)吸附。

物理吸附：
主要發(fā)生在活性炭去除液相和氣相中雜質(zhì)的過程中。活性炭的多孔結(jié)構(gòu)提供了大量的表面積，從而使其非常容易達(dá)到吸收收集 雜質(zhì)的目的。就象磁力一樣，所有的分子之間都具有相互引力。正因?yàn)槿绱?，活性炭孔壁上的大量的分子可以產(chǎn)生強(qiáng)大的引力，從 而達(dá)到將介質(zhì)中的雜質(zhì)吸引到孔徑中的目的。必須指出的是，這些被吸附的雜質(zhì)的分子直徑必須是要小于活性炭的孔徑，這樣才可能保證雜質(zhì)被吸收到孔徑中。這也就是 為什么我們通過不斷地改變原材料和活化條件來創(chuàng)造具有不同的孔徑結(jié)構(gòu)的活性炭，從而適用于各種雜質(zhì)吸收的應(yīng)用。

化學(xué)吸附：
除了物理吸附之外，化學(xué)反應(yīng)也經(jīng)常發(fā)生在活性炭的表面?；钚蕴坎粌H含碳，而且在其表面含有少量的化學(xué)結(jié)合、功能團(tuán)形式的氧和氫，例如羧基、羥基、酚類、內(nèi)脂類、醌類、醚類等。 這些表面上含有地氧化物或絡(luò)合物可以與被吸附的物質(zhì)發(fā)生化學(xué)反應(yīng)，從而與被吸附物質(zhì)結(jié)合聚集到活性炭的表面?；钚蕴康奈秸巧鲜龆N吸附綜合作用的結(jié)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.
