Catalytic wet oxidation of dyhouse effluents with Cu/Al2O3 catalyst at atmospheric pressure |
초록 |
Catalytic wet oxidation using Cu/Al2O3 catalyst and H2O2 was employed for the treatment of dyehouse effluents. The method was found to be efficient for the removal of both TOC and color at atmospheric pressure. The oxidation was based on hydroxyl radical(HO) produced from the dissociation of H2O2. The removal efficiency was strongly related to the consumption of hydroxyl radical.The oxidation rate was affected by amount of H2O2 and when small amount of H2O2 was used, the removal of color did proceed but the TOC concentration remained unchanged. This result indicated that there were two steps involved in the oxidation. At first occurred the breakdown of the large dye molecules into smaller molecules of organics which were then degraded consecutively into carbon dioxide and water. The surface of copper particles in Cu/Al2O3 catalyst provided sites not only for the activation of H2O2 dissociation to give hydroxyl radicals, but also for the adsorption of the organic dye molecules. |
