摘　　要：分别用常规电沉积法和超声电沉积法制备了掺Bi和不掺Bi的4种二氧化铅电极,用加速寿命实验对比了电极的寿命,通过电氧化降解含苯酚废水实验对比了电极的电解处理效果,用扫描电镜表征了电极的表面形貌。结果表明:在电沉积过程中引入超声波和掺Bi有利于提高二氧化铅电极的电催化性能,引入超声波更有利于延长电极的寿命。Four kinds of PbO2 electrodes of doping and non-doping Bismuth were prepared by electro-deposition and ultrasonic-associated electro-deposition. There lifes were contrasted by accelerated life test. Phenol solution was trea- ted by the electrodes. And the effect of electrolysis was tested. The morphology of surface coating was charatctered by scanning electron microscopy. The results show that PbO2 electrode＇s life is longer by ultrasonic-associated electro-depo- sition than by electro-deposition, and bismuth-doped electrode＇s electro-catalytic property is better.
