MORENO, Juan C; SARRIA, Víctor M; POLO, Ángel D y GIRALDO, Liliana. Evaluation of the Hydrogen Peroxide in the Oxidation of Phenol with Iron Supported on Activated Carbon Cloth. Inf. tecnol. [online]. 2007, vol.18, n.2, pp.67-72. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642007000200010.
This study presents the generation and evaluation of three different materials containing activated carbon and iron for the heterogeneous Fenton degradation of phenol. Three different materials: (i) commercial cloth containing activated carbon, and (ii) pellet activated carbon and (iii) a chemically activated carbon with KOH, were explored to support iron by means of impregnation. These three materials were used for the catalytic degradation of phenol with H2O2. The oxidation was performed at 42°C, pH between 2,0-2,5, atmospheric pressure, an initial phenol concentration of 0,01064M and H2O2 0.89M. A relation of impregnation of 1,39gFe/gAC is obtained on the activated carbon cloth. During the oxidation of phenol, the disappearance of the H2O2 was followed as an indirect indication of the kinetics, reaching a minimal concentration of 0.002M of H2O2 by the cloth and the pellet activated carbon. The study shows that the use of cloth activated carbon as catalytic support for the decomposition of phenol is competitive with other conventional porous materials.
