摘要
采用电沉积法制备了Ti/MnO_2/PbO_2电极并用其对质量浓度为20 mg/L 的罗丹明 B 模拟废水进行了电催化降解实验。实验结果表明:原水 pH 为4.95无须调节废水的 pH;最佳电解实验条件为:支持电解质 Na_2SO_4浓度0.09 mol/L电解电流密度40 mA/cm^2处理时间40 min在此条件下罗丹明 B 的去除率接近100%。
Ti/MnO2/PbO2 electrode was prepared by electrodeposition and used in the electrocatalytic degradation of Rhodamine B in the simulated wastewater with 20 mg/L. The optimum process conditions were determined as follows： initial wastewater pH 4.95, electrolyte Na2 SO4 concentration 0.09 mob/L, current density 40 mA/cm^2, treatment time 40 min. Under these conditions, the removal of Rhodamine B can come up to about 100%.
