  • 摘要: 研究了在常压条件下,水合肼还原3种模拟偶氮染料废水并使其脱色,脱色效果用酶标仪测定,其结果表明,脱色效果较好,脱色率最高可达99%.对常压及不同温度条件下水合肼还原模拟甲基橙废水的脱色反应动力学行为及反应活化能进行了研究,结果表明,反应活化能Ea=59.236 kJ·mol-1.在常压条件下,反应符合一级动力学反应.反应产物用GC-MS、1H-NMR测定,并对反应机理进行了初步探讨.
    Abstract: This paper studied decolorization of three azo-dyes by hydrazine hydrate under ambient conditions. The results show that hydrazine hydrate achieved a decolorization rate as high as 99% in the azo-dye decolorization process, and the decolorization rate is positively correlated with pH. The kinetic of methyl-orange decolorization process was also studied. The decolorization of Methyl-Orange follows the first order reaction and the activation energy is 59.236 kJ穖ol-1. Results of GC-MS and 1H-NMR analysis of the reaction products indicate that the decolorization procedure is done by azo bond cleavage.
