| dc.description.abstract | Activated carbon samples were prepared and characterized from two novel forestry precursors by one-step chemical activationwith ZnCl2. The adsorption capacities of the adsorbents were tested with methylene blue in monocomponent synthetic solutionand with heavy metals from polluted river water. The specific surface areas (SBET) of the produced activated carbons were 1278and 1404 m2/g. Further characterization was carried out by FTIR, RAMAN spectroscopy, XRD and FESEM analysis. The porestructure of both activated carbons was predominantly microporous with presence of mesopores. The maximum methylene blue(MB) adsorption capacities for both activated carbons were 250 mg/g and 357 mg/g. MB kinetic experiments were carried outand the influence of the initial MB concentration and the activated carbon dosage was evaluated. The samples reached removallevels close to 100% during the first 5 min of experiments with dissolved As(V) and Pb(II) in the polluted river water, reducingthe concentration of these elements until levels below the local water quality standards. | |
