Ti/RuO₂电极高效降解RB19染料废水的研究

Study on Efficient Degradation of RB19 Dye Wastewater by Ti/RuO₂ Electrode

蒽醌染料产量大,用途广泛,结构中含有毒性较大的基团,一旦流入水环境中,对动植物的生长发育和人类的器官功能造成不可逆转的伤害。本文采用循环伏安法研究了活性蓝19 (RB19)在Ti/RuO2电极上的电化学氧化行为。此外,探究了以Ti/RuO2电极作为阳极电化学降解RB19模拟废水的最佳工艺参数。实验结果表明,在最佳条件下,RB19脱色率为80.8%,CODCr去除率为31.2%。Ti/RuO2电极对RB19的电化学降解效率较高,是一种理想的电极材料。

Anthraquinone dye has large yield, widely used, and contains more toxic groups in its structure. Once it flows into the water environment, it causes irreversible damage to the growth and development of plants and animals and people’s organ functions. The electrochemical oxidation behavior of reactive blue 19 (RB19) on Ti/RuO2 electrode was studied by cyclic voltammetry. In addition, the optimum process parameters of electrochemical degradation of RB19 simulated wastewater using Ti/RuO2 electrode as anode were investigated. The results showed that the decolorization rate of RB19 was 80.8% and the removal rate of CODCr was 31.2%. Ti/RuO2 electrode had high electrochemical degradation efficiency for RB19 and was an ideal electrode material.
