    摘要: This study investigated the aniline oxidation at various conditions, namely, pH, H(2)O(2) dose, Fe(2+) dose, and aniline concentration, as well as the effects of inorganic ion concentrations on the electro-Fenton and fluidized-bed Fenton processes. Aniline degradation depended on the H(2)O(2) and Fe(2+) dose for both processes. The results showed that both processes had the best aniline oxidation efficiency at pH 2.8-3.2. In the electro-Fenton process, approximately 95% of the aniline was removed after 60 min. While the SiO(2) carrier contents of fluidized-bed Fenton process was adjusted to 74 g/L, the aniline was gradually removed, and the degradation rate finally reached 83%. The inhibition effect of phosphate ions on aniline oxidation on both processes was more significant than that of chloride ions. Chloride ions have higher inhibition ability on aniline oxidation in the fluidized-bed Fenton process than in the electro-Fenton process. However, the inhibition of phosphate ions on aniline oxidation in the electro-Fenton process was more obvious than in the fluidized-bed Fenton process. DOI: 10.1061/(ASCE)EE.1943-7870.0000325.
