Abstract:	,6-Dimethylaniline was oxidized using the fluidized-bed Fenton process. This study examined the effects of pH, ferrous ion, hydrogen peroxide and 2,6-dimethylaniline concentrations. Results showed that the optimum pH for removing 2,6-dimethylaniline was 3. Ferrous ion and hydrogen peroxide concentrations were the important parameters in 2,6-dimethylaniline degradation. Increasing ferrous ion and hydrogen peroxide concentrations can enhance the degradation efficiency of 2,6-dimethylaniline. However, excess amounts of ferrous ions and hydrogen peroxide can cause scavenging effects in the reaction, thus decreasing the 2,6-dimethylaniline removal efficiency. The optimum concentrations of ferrous ion and hydrogen peroxide for degrading 1 mM of 2,6-dimethylaniline were 2.5 mM and 10 mM, respectively. In addition, the fluidized-bed Fenton process was proven to have higher degradation ability than the conventional Fenton process.
