Activated carbon adsorption mechanism

Activated carbon adsorption mechanism:
activatedcarbon is a carbon black powder, granules or pellets with a porous amorphous carbon, primarily composed of carbon,GHD IV Straighteners, also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine. Also has a fine architecture like graphite,GHD MK4 Pure Straighteners, yet smaller grain size, floor between the random accumulation. Has a larger surface place (500 ~ 1,000 m 2 / g), has a strong adsorption ashore the surface in the adsorption of its gas, liquid or colloidal solids; for gas, fluid, adsorbed mass of stimulated carbon tin be near to their quality. The selective adsorption of non-polar substances extra accessible than the adsorption of polar substances. In the same array of substances, the boiling point of the stuff more easily the higher the adsorption, the greater the oppression the lower the temperature the greater the concentration, the greater the adsorption capacity. Instead, decompression, temperature is conducive to gas desorption. Commonly secondhand in gas adsorption, isolation and purification, solvent resumption, sugar, fuel, glycerol,GHD Straighteners NZ, drugs bleaching surrogate, water and refrigerator deodorant, gas mask canisters in the agency, also be used as catalysts or metal salts the catalyst carrier. Early production of activated carbon materials as lumber, hard shell or beast bones, and later primarily coal, by distillation, activated carbon creation methods won are: ① steam, gas activation means. Use of water vapor or carbon dioxide in the 850 ~ 900 ℃ activated carbon. ② chemical activation. Gases released by the activation agent, or activator impregnated materials, tall temperature manipulation tin be activated carbon.
activated carbon microcrystalline structure, crystallite entirely irregular preparation of the crystal in micropores (radius fewer than 20 Egyptian 〔〕 = 10-10 m),GHD Green Butterfly 2011, the conversion pore (radius 20 1000), massive hole (radius 1000 100000), it has great inner surface, specific surface area of ​​500 to 1700 m 2 / gram. This determination has a nice activated carbon adsorption,GHD Carry Case & Heat Mat, wastewater and consume gas can be adsorbed metal ions, toxic gases, alphabetical pollutants,GHD Deluxe Midnight 2011, colors and so on. Industrial applying of activated carbon also requires mechanical strength, dress resistance, and its structure to stabilize the adsorption energy necessitated is small, in mandate to facilitate regeneration. Activated carbon for oil, drinks, food, drinking water, bleaching, odor removal, gas separation, solvent recovery and air-conditioning, gas masks as a catalyst patronize and adsorbent.
