摘要
以草酸铁络合物/H2O2作光氧化剂,利用紫外光对水溶性染料靛红进行了光氧化降解试验研究。结果表明,在pH值为3,[Fe(Ⅲ)]/[C2O42-]=1/3,H2O2为100 mg/L条件下,光照30 min后,质量浓度为30 mg/L的染料溶液其脱色率达到98.5%,COD去除率为54.4%。与UV/Fe3+、UV/H2O2、UV/草酸等光氧化体系相比,脱色效果较为明显。
Taking ferrioxalate complexes/H2O2/UV as photo-oxidant, the photo-oxidation degradation of dyes indigo carmine was studied by use of UV light. The results show that under the condition of pH = 3, [Fe（ Ⅲ ） ]/[C2O4^2-] = 1/ 3, and H2O2 = 100 mg/L, the dye solution with a concentration of 30 mg/L was decolorized by 98.5% in 30 minutes, and the removal efficiency of COD was 54.4%. Compared with other photo-oxidation systems, such as UV/Fe^3＋ , UV/ H2O2, and UV/oxalic acid, the ferrioxalate complexes/H2O2/UV system is more effective.
