摘要

在模型染料溶液和实际染料废水上，研究了锰催化剂配合物(MnTACN)对H2O2/UV高级氧化工艺处理效率的提高。实验结果以吸光度(A)和总有机碳(TOC)减少量进行评价。通过高分辨率气相色谱/质谱分析鉴定了模型染料溶液的主要降解产物。此外，还测定了H2O2/UV/MnTACN处理后的最终反应溶液对费氏弧菌的毒性。结果表明，在不同浓度的催化剂溶液中加入H2O2/UV/MnTACN体系，对模型染料溶液和实际染料废水的脱色率都比H2O2/UV体系提高了。

Enhanced photocatalytic oxidation of reactive dye using manganese catalyst complex

In this work, the treatment efficiency of advanced oxidation processes H2O2/UV enhanced by the addition of a manganese catalyst complex (MnTACN) was investigated on a model dye solution and a real dye-house effluent. The experimental results were evaluated in terms of absorbance (A) and total organic carbon (TOC) reduction. The major degradation products of the model dye solution were identified by high resolution gas chromatography/mass spectrometry analyses. In addition, the toxicity of the final reaction solution after H2O2/UV/MnTACN treatment to Vibrio fischeri bacteria was determined. The results showed that the addition of the H2O2/UV/MnTACN system at in different concentrations of the catalyst solution increased enhance the decolourization rate compared to H2O2/UV for both the model dye solution and real dye-house effluent.
