Activated carbon adsorption mechanism

Activated carbon adsorption mechanism:
activatedcarbon is a carbon black powder, granules or pellets with a porous amorphous carbon, effectively composed of carbon,GHD Red Straighteners, also contains a small sum of oxygen, hydrogen, sulfur, nitrogen, chlorine. Also has a fine structure like graphite, but smaller grain size, layer among the irregular collection. Has a larger surface area (500 ~ 1,000 m 2 / g),GHD IV Pink Straighteners, has a strong adsorption on the surface in the adsorption of its gas, liquid or colloidal solids; for gas, liquid, adsorbed hunk of activated carbon can be near to their quality. The selective adsorption of non-polar materials extra lightly than the adsorption of polar substances. In the same sequence of substances,GHD, the boiling point of the stuff more easily the higher the adsorption, the greater the pressure the lower the temperature the greater the concentration, the greater the adsorption capacity. Instead,GHD Green Straighteners, decompression, temperature is favorable to gas desorption. Commonly accustomed in gas adsorption, separation and purification, solvent recovery, sugar, oil, glycerol, pills bleaching deputy, water and refrigerator deodorant, gas mask canisters in the agent, also be accustom as catalysts alternatively metal salts the catalyst carrier. Early making of activated carbon materials as lumber, hard shell or animal bones, and later primarily coal, by distillation, activated carbon production 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 along the activation agent, or activator impregnated materials, lofty temperature management can be activated carbon.
refreshed carbon microcrystalline structure, crystallite entirely irregular arrangement of the crystal in micropores (radius fewer than 20 Egyptian 〔〕 = 10-10 m), the conversion pore (radius 20 1000), massive chasm (radius 1000 100000), it has magnificent internal surface,GHD Straighteners NZ, characteristic surface district of ​​500 to 1700 m 2 / gram. This determination has a agreeable activated carbon adsorption, wastewater and waste gas can be adsorbed metal ions, toxic gases, organic pollutants,GHD Leopard Grain, colors and so aboard. Industrial applying of activated carbon also requires mechanical strength, wear resistance, and its architecture to stabilize the adsorption stamina required is small, in mandate to assist regeneration. Activated carbon as oil, beverages, food, drinking water, bleaching, scent removal, gas detachment, solvent resumption and air-conditioning, gas masks for a catalyst aid and adsorbent.
