摘要：In this work, the Fenton-like decolorization of anazo dye, Acid Red 1 (AR1) by Fe–ball clay (Fe–BC) catalyst wasstudied.The effects of different reaction parameters such as initial iron ions loading on ball clay (BC), catalyst dosage, initial concentration of hydrogen peroxide [H2O2]0 and AR1 [AR1]0,reaction temperature and initial solution pH on the decolorization of AR1 were assessed.The best reacting conditions were found to be 1.0 wt.% of iron ions loading on BC,catalyst dosage = 5.0 g L-1, initial solution pH = 2.5, [H2O2]0 = 12mM, [AR1]0 of 50 mg L-1 at temperature 30 °C.Under these conditions, 99% decolorization efficiency of AR1 was achieved within 180 min of reaction.The results indicated that Fe-BCwas a promising catalyst for the heterogeneous Fenton system.
