  • Activated carbon cloth: a potential adsorbing/oxidizing catalyst for phenolic wastewater

    An investigation into the use of activated carbon cloth (ACC) as a potential adsorbent and/or catalyst for oxidation processes is reported. The extent of increase/decrease of oxidation/adsorption of phenol, as measured by total organic carbon content (%), is explained by considering the effects of the oxidants such as ozone and hydrogen peroxide on the activated carbon cloth. Results also show ...

  • Testing monolithic activated carbon adsorbers for in-line removal of organic micropollutants

    Anthropogenic organic micropollutants (OMP) occur along the whole urban water cycle including drinking water. Various OMP can be efficiently adsorbed onto activated carbon. In the present study a commercial monolithic adsorber (MA), originally developed for gas treatment, was examined for the removal of OMP from drinking water. As a promising advantage, the adsorber can be introduced into ...

  • Influence of carbon nanotubes on the bioavailability of fluoranthene

    Concurrent with the increase in the use of carbon nanotubes (CNTs) in society is the increase in their introduction into the environment. CNTs cause adverse effects themselves and they have the potential to adsorb contaminants such as polycyclic aromatic hydrocarbons (PAHs). Though CNTs have a high adsorption capacity for PAHs and these contaminants can co‐occur in the environment, few studies ...

  • Removing mercury with activated carbon

    Granular Activated carbon is effective at physically adsorbing trace components from gas streams due to its high population of micropores; however, the capacity is low. By impregnating the granular activated carbon with a compound that will chemically react with the mercury, capacity can be enhanced. It is imperative that not only must the mercury be removed to non-detectable levels but that it ...

  • Studies on competitive adsorption of dyes onto carbon (XC-72) and regeneration of adsorbent

    Carbon as an adsorbent has been widely studied for wastewater treatment, but the regeneration of adsorbent has been scarcely reported. In this paper, an economical and environmental method was applied to regenerate carbon (XC-72). Results showed that both anhydrous ethanol and deionized water did not obtain optimal effect for the desorption of Acid Orange 7, Ponceau 2R and Rhodamine B, but the ...

  • Carbon nanotubes and graphenes as adsorbents for adsorption of lead ions from water: a review

    Nanomaterials have wide applications as sorbents for water purification as they have high selectivity as well as capacity for organic/inorganic pollutants and contaminants in aqueous solutions. Non-essential toxic heavy metals present in water have become a major cause of many diseases, ageing, and genetic problems. Carbon-based nanomaterials have generated great interest in their use as sorbent ...

  • Oxidized fulvic acid adsorption on activated carbon

    This study evaluates and compares the parameters of equilibrium adsorption from aqueous solutions of river fulvic acids (FA) and peat fulvic acids. Compared to peat FA, the river FA had lower biodegradable dissolved organic carbon (BDOC). We observed a tendency for correlation between change of Gibbs free energy of adsorption and BDOC value. A chlorination dose of 1.4 mg L−1 did not ...

  • Adsorption of methylene blue and Congo red from aqueous solution by activated carbon and carbon nanotubes

    This study was conducted to determine the adsorption removal of dyes by powdered activated carbon (PAC, Norit) and multi-walled carbon nanotubes (MWCNTs, Chinese Academy of Science) from an aqueous solution. Methylene blue (MB) and Congo red (CR) were selected as model compounds. The adsorbents tested have a high surface area (PAC 835 m2/g, MWCNTs 358 m2/g) and a well-developed porous ...
