Abstract
The degradation of acid magenta in aqueous solution by Fenton’s reagent was studied. After 30 min, the 97% removal of acid magenta in water (pH=3, T=30℃) was achieved when the initial concentrations of Fe2+, H2O2 and acid magenta were 0.06 mmol/L, 0.3 mmol/L and 20 mg/L, respectively. Increasing the reaction temperature was beneficial for the degradation of acid magenta, but not obvious. Based on the Arrhenius equation, the activation energy (Ea) was calculated to be 11.63 kJ/mol from rate constants at different temperatures. The degradation of acid magenta by Fenton’s reagent was inhibited by the presence of C1–, and the rate of acid magenta removal decreased with increasing of the concentration of C1–. The presence of SO2-4 and NO-3 also decreased the oxidative activity of Fenton’s reagent.
