Ti/IrO_2-RuO_2电极降解苯酚红废水

Degradation of phenol red wastewater by Ti/IrO_2-RuO_2 electrode

利用热分解法制备Ti/IrO_2-RuO_2电极,以该电极为阳极处理苯酚红(PR),并优化其最佳处理条件。结果表明:在电流密度为15 mA·cm-2、电解质Na2SO4浓度为6.0 g·L-1、废水溶液起始pH=7、反应温度为40℃时,处理120 min后PR废水的降解率为74.5%。

Ti/IrO2-RuO2 electrode was prepared by thermal decomposition method. Phenol red (PR) was treated with the electrode as an anode, and the optimal treatment conditions were optimized. The results showed that the degradation rate of PR wastewater was 74.5% after 120 min treatment with current density of 15 mA cm^-2, electrolyte Na2SO4 concentration of 6.0 g L^-1, initial pH of wastewater solution = 7 and reaction temperature of 40 C.
