Removal of Cu(II), Pb(II), and Ni(II) by Adsorption onto Activated Carbon Cloths

摘要: The adsorption of three metal ions, Cu(II), Ni(II), and Pb(II), is performed by activated carbon cloths (ACC). Two adsorbents, CS 1501 (with more than 96% micropore volume) RS 1301 32% mesopore volume), are studied. Batch experiments carried out to assess kinetic equilibrium parameters. They allow data, transfer coefficients, maximum capacities be computed. These parameters show the fast external film ions on fibers, because their low diameter (10 μm). Intraparticular diffusion coefficients lower those obtained with a granular carbon, but agree literature values for GAC. dependency ion size ACC porosity, largest cation Pb(II) being adsorbed mesoporous cloth. pH effect studied, edges determined. short, only 2 units, located below precipitation edges.
