电动降解处理酸性品红染料废水的研究

Degradation treatment of acid violet red dye wastewater by electrokinetic method

研究了酸性品红在电动降解作用下的定向迁移及降解反应。在电场作用下,酸性品红定向迁移到阴极附近区域,聚集到一定浓度时被电动降解除去。考察了pH值、电压及电解质浓度对酸性品红电动降解的影响。实验表明,较好的酸性品红分子降解工艺条件为:pH=5,电压为18 V,电解质浓度为3 mg/L。

The transfering and subsequent degradation process of acid electroanalysis reaction had been investigated. region near the cathode first, and then is deco The results showed that violet red dye wastewater via the the acid violet red transfer to the reposed by electrolysis when gathering to a certain concen- tration, pH, voltage and electrolyte concentration have a significantly effect on the degradation reaction of acid violet red in wastewater. The optimum experimental conditions are as follows：pH 5, the voltage 18 V, and electrolyte concentration 3 mg/L,in which acid violet red can achieve the best removal efficiency.
