| 摘 要： | 本文介绍了用含不同组分的铁氧体(M-铁氧体)作为催化剂,对印染废水进行催化空气氧化脱色的试验研究.实验发现Ni-铁氧体对不溶性还原染料废液有较好的催化脱色能力,脱色率通常可达90％以上.红外光谱分析结果表明,Ni-铁氧体参与的不溶性还原染料废液的催化脱色反应是通过将染液中的助剂保险粉彻底氧化,从而使染料转化为不溶性沉淀物被分离而完成的.

| Abstract: | Reported in this paper is an experimental study that M-ferrites were used as a catalyst to treat dyeing wastewater for decolorization by the catalysis of air oxidation, the catalysts were a series of M-ferrltcs which were composed of different components. It was found that Ni-fcrrite had a good capacity for catalyst decolonization towards the wastewater containing insoluble reductive dyes, and its decolorized rate was over 90%. The results of infi ared spectrum analysis indicated that the catalyst Ni-frrrite for decolorization reaction to the insoluble reductive dyeing wastewater was reacted with complete oxidation of the auxiliary, sodium hydrosulphite (Na2S2O4)in the wastewater so as to coovert the dye into insoluble sediment, which then was teparated. |
