摘要
研究了Fenton试剂对五种模拟活性染料染液的脱色和COD去除情况。结果表明,常温时,浓度为400mg/L的活性染料染液在Fenton试剂(Fe2+浓度为30mg/L,H2O2浓度为1mL/L)作用下反应60min,脱色率达到了95%以上,COD去除率达到55%～60%。
Five kinds of simulated reactive dyeing effluents was treated with Fenton reagent, performance of decolorization ratio and COD removal of these dyes were investigated. When the concentration of reactive dye is 400 mg/L, Fe^2＋30 mg/L, H2O2 1mL/L, reaction 60 minutes at room temperature, the decolorization efficiency was up to more than 95 % and COD removal efficiency up to 55% - 60 %.
