摘　　要：以钢渣为铁源,利用光Fenton法降解甲基橙,考察了不同pH、钢渣添加量和双氧水浓度对甲基橙降解速率的影响。结果表明,甲基橙降解速率与钢渣中Fe3+溶出速率有关,随pH的降低、钢渣添加量的增加降解速率明显增大。甲基橙降解速率随双氧水含量的增加先增后减,过高的双氧水含量不利于甲基橙降解速率的提高。紫外光对降解速率的提高在降解后期尤为显著。The steel slag as Fe source was applied to the degradation of methyl orange by photo-fenton method. Experimental variables such as initial pH, steel slag dosage and H2O2 dose were studied. The results showed that the decolorization efficiency was enhanced with the increase of steel slag dosage and the lower pH. For H2O2, there was an optimal dose for H2O2 for the higher decolorization efficiency and superabundant dose made against for the increase ofdecolorization efficiency. UV illumination was more prominent for the decolorization efficiency during the later period.
