Activated carbon adsorption mechanism

Activated carbon adsorption mechanism:
carbon activatedcarbon is a dark abrasive, granules alternatively pellets of amorphous porous carbon, the main component of carbon, also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine. Also has a fine structure as graphite, yet the smaller grains, among layers of irregular accumulation. Has a large surface area (500 to 1000 m 2 / g), has a strong adsorption in the adsorption above the surface it's gas, liquid or colloidal solids; for gas, fluid, adsorption stuff quality can be near to carbon their quality. The adsorption is selective, non-polar material is easier than the adsorption of polar materials. In the same sequence of substances, the higher the boiling point of the material extra easily adsorbed, the greater the pressure the lower the temperature the greater the concentration, the greater the adsorption. Instead, decompression,GHD IV Salon Straighteners, gas desorption temperature is profitable. Commonly accustomed in gas adsorption, separation and purification, solvent recovery, sugar,GHD Purple Butterfly 2011, oil, glycerin, narcotics, bleaching agents, drinking water and refrigerator deodorant, gas mask canisters in the surrogate, also used as catalysts or metal salts catalyst conveyor. Early production of activated carbon materials as lumber, hard shell or animal bones, and later effectively in coal, by distillation, activated carbon product won behind processing methods are: ① steam, gas activation means. Use of water vapor or carbon dioxide in the 850 ~ 900 ℃ activated carbon. ② chemical activation means. The use of activator release of gas,GHD Green Butterfly 2011, or activator impregnated materials, lofty temperature treatment can be activated.
stimulated carbon with a microcrystalline structure, the microcrystalline array altogether uneven crystals in micropores (radius fewer than 20 [angstroms] = 10-10 m), the transition pore (radius 20 1000), colossal cavity (radius 1000 100000), it has great inner surface, the surface zone of ​​500 apt 1700 m 2 / gram. This determines the stimulated carbon has a good adsorption, tin sponge water and gas in the metal ions, toxic gases, organic pollutants, colors, etc. Industrial petition of activated carbon also requires mechanical strength,GHD Midnight Gift Set 2011, wear resistance, and it sought to stabilize the building, adsorption vigor necessitated namely small, in order to assist regeneration. Activated carbon for fuel,GHD Red Butterfly 2011, beverages, edible,GHD NZ, drinking water, bleaching, de-taste, gas disjunction, solvent revitalization and air-conditioning, and gas masks as a catalyst adsorbent.
