【摘要】 用电沉积方法制备了Ti/SnO2+Sb2O3/PbO2,Ti/SnO2+Sb2O3/Bi-PbO2,Ti/PbO2三种二氧化铅电极,采用加速寿命试验对比了电极的寿命,采用扫描电镜表征了电极的表面形貌,并将所制备的电极用于处理苯酚溶液和含铜离子的溶液,分析了电解处理的效果。结果表明:未掺铋二氧化铅电极的加速寿命最长,且其处理的含铜废水可达国家排放标准,但掺铋电极的电催化性能更高。更多还原

【Abstract】 Ti/SnO2+Sb2O3/PbO2,Ti/SnO2+Sb2O3/Bi-PbO2 and Ti/PbO2 electrodes were prepared by electrodeposition.There lifes were contrasted by accelerated life test.The morphology of surface coating was charatctered by scanning electron microscopy.Phenol solution and solution containing copper ions were treated by the electrodes.And the effect of electrolysis was tested.The results show that Ti/SnO2+Sb2O3/PbO2’s life is the longest of the three electrodes and wastewater containing copper ions treated by the electrode can meet the national standard.But bismuth-doped electrode’s electro-catalytic property is better.更多还原
