| 摘 要： | 研究了用电沉积法制备掺杂钛基二氧化铅系列电极的制备工艺，制备出掺杂铁、钴、镍的3种钛基PbO2电极，并通过对苯酚的降解实验研究了电极的电催化性能．表明3种掺杂改性钛基PbO2电极具有较好的电催化性能，特别是明显地降低了槽电压，且降解过程符合一级反应动力学关系，确定该物质的降解过程符合准一级反应，并得到了反应速率常数．

| Abstract: | In this paper , doped lead dioxide electrode on Ti substrates was produced by electrodeposition. Electro- catalytic characteristics of the three typical electrodes were investigated through its degradation experiments of phenolic wastewater in order to get the best preparation technology of the electro-catalytic anode. Taking phenol as model substrate , the electro-catalytic characteristics of prepared anodes were investigated. Meanwhile, the reaction dynamics of phenol was studied and the pseudo-first order rate was calculated. |
