不同电极材料电催化降解分散大红实验研究

Influences of Electrode Materials on the Catalytic Degradation of Disperse Red

不同二维电极材料及三维电极处理分散大红染料。结果显示,金属电极作为阴极对染料的脱色效果优于碳电极。加入少量活性炭粉末,可以提高降解效果,减少次生气味污染。三维电极对高浓度染料溶液的处理效果显著优于二维电极。

Different two - dimensional and three - dimensional electrode materials were used to degrade the disperse red. The result showed that the color removal rates by metal electrodes were higher than those by carbon fiber electrode. Adding activated car- loon power into the electric catalysis system could enhance the degradation efficiency and reduce the secondary odor pollution. The, color removal efficiency of high concentrations of disperse red solution by three - dimensional electrode systems was superior to two - dimensional electrode.
