| 摘 要： | 采用电沉积法制备了Ti／MnO2／PbO2电极，并用其对质量浓度为20mg／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NazSO4浓度0．09mol／L，电解电流密度40mA／cm^2，处理时间40min，在此条件下罗丹明B的去除率接近100％。

| Abstract: | Ti/MnO_2/PbO_2 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 Na_2SO_4 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%. |
