  • 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 ...

  • 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 ...

  • 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 ...

  • Comparison between Brazilian agro-wastes and activated carbon as adsorbents to remove Ni(II) from aqueous solutions

    This research was performed to find an alternative, low-cost, competitive, locally available and efficient adsorbent to treat nickel (Ni) containing effluents. For this purpose, several Brazilian agro-wastes like sugarcane bagasse (SCB), passion fruit wastes (PFW), orange peel (OP) and pineapple peel (PP) were compared with an activated carbon (AC). The adsorbents were characterized. Effects ...

  • Methylene blue removal using a low-cost activated carbon adsorbent from tobacco stems: kinetic and equilibrium studies

    The aim of this study was to prepare activated carbon from tobacco stalks using microwave heating. The prepared activated carbon was applied as an adsorbent in methylene blue (MB) removal from water. The optimum conditions for activated carbon preparation were a radiation power of 280 W for a period of 6 minutes after the impregnation of the precursor material with 30% ZnCl2 for 24 hours. The ...

  • Activated carbon prepared from coffee pulp: potential adsorbent of organic contaminants in aqueous solution

    The processing of coffee beans generates large amounts of solid and liquid residues. The solid residues (pulp, husk and parchment) represent a serious environmental problem and do not have an adequate disposal mechanism. In this work, activated carbons (ACs) for adsorption of organic compounds were prepared from coffee pulp by controlled temperature at different pulp/Na2HPO4 ratios ...

  • Methylene blue removal by carbonized textile sludge-based adsorbent

    Colored effluent and a large amount of sludge are major pollutant sources derived from textile industry activity. In this research, the idea for converting textile sludge into a potential adsorbent was conducted through a carbonization process in order to solve the colored effluent problem. Textile sludge was carbonized at a temperature ranging from 400 to 800 °C in the absence of oxygen. ...

  • Removal of ammoniacal nitrogen and COD from semi-aerobic landfill leachate using low-cost activated carbon?zeolite composite adsorbent

    A carbon-zeolite composite adsorbent has been studied for COD and ammoniacal nitrogen removal in semi-aerobic landfill leachate. The optimum conditions for adsorption in the batch study occurred at pH 7, shaking speed of 200 rpm, and contact time of 105 min. The Langmuir isotherms corresponded slightly better than Freundlich isotherm for both ammoniacal nitrogen and COD removals. The Langmuir ...

  • 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 ...
