2,4-Dichlorophenol degradation by heterogeneous Fenton like reaction using carbon-Fe catalysts
Catalytic degradation of simulated 2,4-dichlorophenol wastewater are investigated by using self-synthesized Fe/activated carbon (AC) catalysts and hydrogen peroxide oxidation agent. Effects of the most relevant operating conditions(pH, catalysts concentration, 2,4-dichlorophenol concentration, H2O2 concentration and reaction temperature) were discussed. The results indicate that the degradation rate of 2,4-dichlorophenol (400mg/L) reach 79.9％ in the presence of Fe/AC(2g/L) and hydrogen peroxide (1％) at pH=3 after 180 minutes under normal temperature and atmospheric pressure. Kinetic studies of the catalytic reaction showed that the degradation reaction of 2,4-dichlorophenol nearly follows the first-order reaction, the reaction constant and activity energy are 0.00626min-1 and 66.50 kJ/mol at 30 ℃, respectively.
