摘　　要：通过电沉积法制备SnO2/Ti电极,同时掺杂Pr对其进行改性,获得Pr改性SnO2/Ti电极。利用SEM和XRD分析方法表征了电极的形貌及结构,以制药厂废水为目标污染物,控制电流强度为0.3A,3.5h后COD由392mg/L降至20mg/L,去除率达94.9%。实验结果表明,Pr改性SnO2/Ti电极具有更好的电催化性能。In this paper, praseodymium was selected as a promoter for SnO2/Ti electrode to improve the electro - catalytic ability by eleetrodeposition in pharmacy wastewater treatment. The mierograph of the electrode surface and the structure of the electrode surface were analyzed by SEM and XRD,respectively.When current intensity was 0.3A,after 3.5h, the removal rate of COD was up to 94.9% from 392 mg/L decreased to 20mg/L. Experimental results show that the electrode had better electro- catalytic ability.
