| contents | Design of an adsorbent employing activated carbon fiber to remove lead C. Cárdenas-López G. Camargo J.C. Moreno-Piraján L. Giraldo Química ion Pb2+ isotherms adsorbent activated fibers Zorflex® activated carbon fibers (ACF), reference FM100 198B, are used beforeand after an oxidizing procedure with H3PO4 to study the adsorption of Pb2+. The point ofzero charge was determined for the modified and unmodified fiber giving values of 2.3 and4.3, respectively. After oxidizing the ACF, the fiber showed to have a greater Pb2+ adsorptioncapacity in comparison with the unmodified fiber, which is related with the acid sites increase,where lead was mainly adsorbed. Determination of the BET area was carried out by nitrogenphysisorption at 77K. ACFs presented superficial areas between 1000 and 1500 m2/g showingmostly, a microporous structure. The preliminary design of an adsorbent using the modifiedfiber is presented where the fiber superior physicochemical properties over the unmodifiedone are observed. 2007 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42932309 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.3 Vol.32 |
