VOCs and activated carbon adsorption of organic compounds can be extracted with a greater difference. Volatile organic compounds with molecular weight increases, the adsorption better, and can be extracted with a molecular weight organics reduced coal columnar activated carbon filter, the adsorption better. This is mainly due to the volatile organic compounds are mainly relatively small number of polar organic compounds, which can be extracted from the organic matter is relatively large polar organics, activated carbon itself can be seen as a non-polar sorbent, non-polar substances in water adsorption capacity is greater than the adsorption capacity of polar substances. Moreover, the adsorbate molecular size and a certain percentage of activated carbon was coal columnar activated carbon, the most favorable adsorption. For less polar molecules, the molecular weight of the bigger, the better absorption. Activated carbon in terms of the elemental composition, 80% -90% consisting of carbon, activated carbon which is also the reason for the hydrophobic adsorbent. Activated carbon in addition to carbon coal columnar activated carbon Which is good, also contains a blend of two types: one is a chemical combination of elements, mainly oxygen and hydrogen from coal columnar activated carbon suppliers, these elements are not entirely due to charring and remain in the char, or in the activation process, non-carbon elements and external surface of the activated carbon chemically bound, such as by steam activation, the activated carbon surface is oxidized or steam oxidation; the other is a blend of ash, it is activated carbon The inorganic part, several elements of activated carbon coal columnar activated carbon price, Shanghai coal columnar activated carbon, water purification by Yu Tai Yu-tai Gongyi City Water Material Co., Ltd.
