辉光放电电解等离子体处理次甲基蓝废水

Degradation of Methylene Blue Wastewater by Glow Discharge Electrolysis Plasma

利用辉光放电电解等离子体技术对次甲基蓝废水的降解进行了研究,详细考察了电压、染料浓度、pH值、催化剂对次甲基蓝降解效果的影响。实验发现,次甲基蓝废水的优化降解条件为:工作电压610 V,pH值3.0,Fe2+催化作用下降解效率明显提高。利用紫外-可见吸收光谱监测了次甲基蓝的降解过程,结果表明,次甲基蓝先被降解成小分子,小分子继而被进一步降解。

Methylene blue wastewater was degraded by glow discharge electrolysis technology. The effect of the factors on the discoloration process such as the voltage, the initial concentration, pH and catalyst was discussed. The optimal degradation conditions were as follows： working voltage 610 V; pH 3.00; The catalyst Fe2 ＋ can promote the degradation of Methylene blue wastewater. The degradation process of Methylene blue was monitored by UV - visible absorption spectra. The results showed that Methylene blue wastewater was degraded into small molecules, and then the small molecules were further degraded.
