| 中文摘要 |
| Fenton试剂与酸性、活性、直接、阳离子、分散和还原6类18种染料反应时,前4类染料在180min内完全脱色,TOC浓度均显着下降。后2类染料的脱色率很低,TOC浓度降低不多。研究了不同金属离子与紫外光的催化下,H22对染料罗丹明B溶液的氧化反应。催化的结果为:Fe2+/UV>Cu2+/UV>Fe2+>Cu2+>Mn2+/UV>Ag+/UV>Mn2+>Ag+.通过与还原蓝RSN溶液的反应,表明Fenton/UV体系中的反应程度大于Fenton及H2O2/UV 2种体系中反应程度的加和,表明紫外光与亚铁离子对H2O2的催化作用存在协同效应。 |
| 英文摘要 |
| kinds of dye solution, including 6 species of cationic, direct, reactive, acidic, reductive and disperse dye were reacted with Fentons reagent. The four formers were decolorized and the concentrations of TOC of them were decreased during 180 min.On the contrary the colority and the TOC of the two latters were reduced lightly. The catalytic function of different metal ions and UV light on the decomposite of Rodamine B was in the sequence of Fe2+/UV>Cu2+/UV>Fe2+>Cu2+>Mn2+/UV>Ag+/UV>Mn2+>Ag+.Vat Blue RSN dye solution was degradated by Fentons reagent, Fenton/UV and H2O2/UV. The oxidation by Fenton/UV was the strongest and even stronger than the arithmetic sum of the other two, which means the synergistic effect of UV and Fe2+ on the function of H2O2. |
