Phenol Degradation by Catalytic Wet Hydrogen Peroxide Oxidation on Fe/Active Carbon Catalyst
2012
A catalyst based on Fe/active carbon (Fe/AC) and H2O2 as oxidant for the catalytic wet hydrogen peroxide oxidation of phenol in aqueous solution was investigated. The results indicate that the degradation rate of phenol(20mg/L) reach 90.5% in the presence of Fe/AC(2g/L) and hydrogen peroxide (0.5 %) at pH value 7 after 5 hours under normal temperature and atmospheric pressure. Kinetic studies of the degradation reaction show that the degradation rate of phenol nearly follows the first-order reaction. The reaction rate constant and activity energy are 0.4162 min-1 and 23.64 kJ/mol at 25°C, respectively.
