【摘要】 研究了铁-碳原电池对活性艳红染料水溶液脱色的影响因素,通过脱色率随pH 值的变化的研究以及用紫外-可见光谱和红外光谱对活性艳红染料水溶液脱色前后的分析,讨论了脱色机理,发现在脱色过程中,染料的结构没有变化,化学吸附去除染料是脱色的主要原因.更多还原

【Abstract】 The factors on tte decolorization of reactive gorgeous red dye aqueoussolution by iron-graphite cell method were studied.The mechanism of decolori-zation was discussed by analyzing the change of decolorizing ratio with thepH value of the solution and the spectra of UV-Vis and IR of the solutionsbefore and after being decolorized.It was found that the structure of the dyedid not change during decolorizing and the decolorization was based on the che-mical adsorption.更多还原
