Fixed-bed Adsorption of Trichloroethylene onto Activated Carbon
The present work deals with the study of the adsorption of Trichloroethylene (TCE) onto a commercial granular activated carbon (GAC). Thermodynamic (batch) and dynamic (fixed-bed column) tests were carried out, under a wide range of operating conditions. In particular, adsorption isotherms were preliminary determined to support the investigation on a fixed-bed column at lab-scale. The main flui...
متن کاملAdsorption of Copper (II) Ions from Aqueous Solution onto Activated Carbon Prepared from Cane Papyrus
The present study evaluates the suitability ofactivated carbon, prepared from Cane Papyrus, a plant that grows naturally and can be found quite easily, which serves as a biological sorbent for removal of Cu2+ ions from aqueous solutions. Fourier transform infra-red analysis for the activated carbon, prepared fromCane Papyrus confirms the presence of amino (–NH), carbonyl (–C=O), and hydroxyl (...

متن کاملCompetitive adsorption of furfural and phenolic compounds onto activated carbon in fixed bed column.
For a multicomponent competitive adsorption of furfural and phenolic compounds, a mathematical model was builtto describe the mass transfer kinetics in a fixed bed column with activated carbon. The effects of competitive adsorption equilibrium constant, axial dispersion, external mass transfer, and intraparticle diffusion resistance on the breakthrough curve were studied for weakly adsorbed com...
متن کاملFixed Bed Adsorption of Acetone and Ammonia onto Oxidized Activated Carbon Fibers
The tailoring of the pore surface chemistry of activated carbon fibers is shown to be an effective method for increasing the removal efficiencies of various contaminants under a fixed bed configuration. An oxidation treatment with nitric and sulfuric acids resulted in a significant increase in the adsorption capacities and breakthrough times. The adsorption kinetics were described by a homogene...
