| 제목 | Catalytic wet oxidation of reactive dyeswith Pt/TiO2 catalyst |
| 초록 | Wet air oxidation is a very attractive and useful technigue for treatment of effluent streams exhibiting high biochemical oxygen demand(BOD) and chemical oxyen demand(COD), but it has a detrimental shortcoming that it should be operated under severe conditions of high pressure(6-17MPa) and high temperature (150-350℃). The severity of the process can be improved by catalytic process. Catalytic wet oxidation is the catalytic oxidation of oxidizable compounds with air or pure oxygen in an aqueous phase. Catalytic wet oxidation of reactive black 5 and reactive blue 19 was carried out on the 5wt% Pt/TiO2 catalyst at 2.3 MPa. Both the reactive dyes in aqueous solution could be destroyed through the catalytic wet oxidation. In addition the nitrogen compound anchoring in the reactive dyes is believed to be converted mainly into N2 gas rather than NO3-, which can become an advantage of the catalytic wet oxidation over the other wastewater treatment methods owing to the less production of nutrient compounds. |
