  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • The Many Uses of Activated Carbon

    Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 ...

  • Chemical production and characterisation of activated carbon from waste 'coffee grounds'

    Activated carbon was prepared from ground–coffee in this study. Experimental results reveal that for the ratio (0, 1 ÷ 0, 3) of coffee grounds to activating agents (ZnCl2, H3PO4) has not noteworthy influence. The rise temperature and carbonisation time respectively, in the interval of 500–700°C and ...

  • Simultaneous activation/sulfurization method for production of sulfurized activated carbons: characterization and Hg(II) adsorption capacity

    As an inexpensive method for modification of activated carbons (ACs), sulfurization has attracted significant attention. However, the resulting sulfurized activated carbons (SACs) often are less porous than the original ACs. In this work, we propose a new method for concurrent sulfurization/activation that can lead to preparation of SACs with more porosity than the corresponding non-sulfurized ...

  • Top 3 Uses of Activated Carbon

    Activated carbon is an effective purifier. It is used to remove organic pollutants from different gaseous, liquid and solid substances. By removing the undesirable organic compounds, activated carbon can successfully remove the odour and taste of these compounds from a wide range of things.  Unlike other purification agents that react with organic compounds and change their nature, activated ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...

  • Adsorption of methylene blue dye onto activated carbons based on agricultural by-products: equilibrium and kinetic studies

    Mixtures of novolac resin and olive stone biomass (20/80 and 40/60 w/w) were cured, pyrolyzed up to 1,000 °C and activated with CO2 under a continuous flow operation (named N20B-cCa and N40B-cCa respectively). Commercial activated charcoal was similarly re-activated with CO2 and used for comparison reasons (AC-a). The characterization of these materials was performed by Fourier ...

  • Production of hydrogen by steam gasification of dehydrochlorinated poly(vinyl chloride) or activated carbon in the presence of various alkali compounds

    Steam gasification of dehydrochlorinated poly(vinyl chloride) (PVC) or activated carbon was carried out in the presence of various alkali compounds at 3.0?MPa and 560°C–660°C in a batch reactor or in a semi-batch reactor with a flow of nitrogen and steam. Hydrogen and sodium carbonate were the main products, and methane and carbon dioxide were the minor products. Yields of hydrogen were high in ...

  • Ozonation and Granular Activated Carbon Filtration the Solution to Many Problems

    This paper explains how ozone is used in the purification of surface water to potable water both as the first treatment stage and as an intermediary stage for the reduction of organics and as a disinfectant. Taste and odour of the water are improved by the oxidation of both organic and inorganic impurities by ozone. Products resulting from algae metabolisms are shown to be easily oxidised by ...

  • Adsorption characteristics of Bisphenol-A on tailored activated carbon in aqueous solutions

    The adsorption behavior of pharmaceuticals and personal care product, Bisphenol-A (BPA), according to four coal-based and four wood-based granular activated carbons modified using outgassing treatment, acidic treatment or alkaline treatment was studied. The adsorption isotherm results indicated that carbon surface acidity played a very important role in the adsorption of BPA. It was found that ...

  • Fluoride sorption using morringa indica –based activated carbon

    Fluoride is an important micro nutrient for the production and maintenance of healthy bones and teeth. Although a certain amount of fluoride gives good protection against dental decay, excess intake of fluoride ions cause dental fluorosis. When the concentration of fluoride is more than 4 mg/L it causes softening of bones, ossification of tendons and ligaments and neurological damage in severe ...
