| 摘 要： | 采用电沉积法分别制备末修饰、掺杂Bi、Cu和Bi+Cu四种钛基PbO2电极,利用扫描电镜(SEM)对制得的4种电极进行了表征.同时用所制得的电极对附子废水进行降解试验.研究表明Bi+Cu混合掺杂的电极能显著改善钛基PbO2电极的性能,对COD的去除率达到67.73%,对氯离子的去除率也能达到43.20%,而未掺杂电极对... |

| Abstract: | Four kinds of lead dioxide electrodes on Ti substrate by electro-deposition were prepared,and the front four electrodes which were normal,doped with Bi,Cu,both Bi and Cu respectively were characterized by using scanning electron microscope.Meanwhile,the electrodes performances were compared by measurement of the removal efficiency of aconitic wastewater on both COD and chlorine ion.It was found that the electrode which doped with Cu+Bi can evidently improve the lead dioxide electrode's performance.The remov... |
