| 摘要: | The fluidized-bed Fenton process is an alternative process that decreases iron sludge from the Fenton reaction by using carriers to crystallize iron on to the surface of the carrier. In this study, the target compound is 2,6-dimethylaniline, which is a carcinogen and difficult to degrade. This study examined the effect of different carriers on the degradation of 2,6-dimethylaniline by a fluidized-bed Fenton process. The six carriers were alumina dioxide (Al2O3), silica dioxide (SiO2), and black, white, brown and coloured gravels. The results revealed that differences in the composition of elements and the structures of each carrier have different effects on the oxidation of 2,6-dimethylaniline. The carriers containing Ca were not suitable for use in the fluidized-bed Fenton process. In contrast, Al2O3 and SiO2 were more efficient at removing 2,6-dimethylaniline, and the pH value was almost stable. Moreover, 2,6-dimethylanililne removal efficiency of Al2O3 was higher compared with the other carriers. Therefore, in this study, Al2O3 was an optimum carrier for the oxidation of 2,6-dimethylaniline. |
