The effect of the amount and adding method of activated carbon on smoke emission of cigarettes was investigated. It was found that the filtration efficiency of ternary compound filter was higher than that of binary compound filter under the influence of plasticizer when the amount of activated carbon was constant. With the increase of the amount of activated carbon, the filtration efficiency of the two kinds of composite filters increases. The effects of the amount of activated carbon on the filtration efficiency of the compounds with different volatiles are different.activated charcoal powder The effects of the amount of activated carbon on the filtration efficiency of the isomers are similar due to their close molecular weight and boiling point. When the dosage is small, the competitive adsorption is easy to occur. The adsorption amount of refractory components such as acetaldehyde is small, and the competition can be reduced by increasing the dosage. The filtration efficiency of refractory components shows an obvious upward trend with the increase of the dosage.The general use of medicinal or chemical pure activated carbon. This kind of activated carbon particles is very fine, in powder form, the total surface area is particularly large, the adsorption capacity is very strong, the adsorption capacity is also very large, is the strongest kind of activated carbon adsorption force. But because the particles are too fine, the flow rate is too slow in the process of chromatography, the operation of pressure or decompression is needed, the procedure is more complicated, and the adsorption selectivity of various components is also poor, so it is less used in chromatography.
Medicinal or chemical pure activated carbon before leaving the factory after impurity treatment and metal limit inspection, can be used directly for chromatography. Industrial activated carbon is not processed by impurities before leaving the factory, often contains metal ions, affecting the separation effect, so it must be treated before use, its treatment methods are two.www.activated-carbon-pellets.com

The organic pollutants themselves are not only highly toxic, but also may generate halogenated disinfection by-products (DBPs) after chlorination disinfection. Meanwhile, the existence of organic compounds will reduce the biological stability of drinking water and lead to the secondary reproduction of microorganisms in the pipe network. Therefore, it is important to reduce the content of organic pollutants in drinking water. Conventional water treatment process has low removal efficiency for organic pollutants, so it is imperative to seek economic and efficient treatment technology. On the basis of giving full play to the advantages of ozone oxidation in the removal of organic matter, ozone catalytic oxidation technology can induce the formation of hydroxyl radical (·OH) with high oxidation ability, which can effectively remove trace organic pollutants in water and reduce the content of ozone oxidation by-products. Therefore, it is a drinking water treatment method with great application prospect.wholesale activated carbon pellet
