| 摘要: | This study investigates the degradation of aniline by the Fered-Fenton process with a plate and rod electrode. The effects of electric current, H2O2, Fe2+, and aniline concentrations on the kinetic models, H2O2 efficiency, and energy consumption in aniline and chemical oxygen demand (COD) removal were examined. The kinetics of aniline degradation using the Fered-Fenton process was second-order. The H2O2, Fe2+, and aniline concentrations affected the COD removal efficiency more than electric current. The kinetics of aniline degradation using the Fered-Fenton process was second-order. In both Fered-Fenton reactor systems, increasing the electric current, H2O2, Fe2+ and aniline concentrations significantly decreased the efficiency of H2O2 in reducing aniline and COD. The reactor design substantially affected the rate constant of aniline degradation. In general, the rate constants of aniline degradation in the plate electrode Fered-Fenton reactor were around 1.1-6.3 times higher than that in the rod electrode Fered-Fenton reactor. At various H2O2 concentrations, the rod electrode Fered-Fenton reactor consumed twice as much energy in removing aniline and COD compared with the plate electrode Fered-Fenton reactor. Additionally, COD removal required twice the energy needed to remove aniline. (c) 2013 American Institute of Chemical Engineers Environ Prog, 33: 410-418, 2014 |
