制备了一种非贵金属阳极-Ti/SnO2+Sb2O3+MnO2/PbO2,并用XRD、SEM进行了表征,计算出了电极的分形维数,测定了该电极在硫酸中的使用寿命和动力学参数,把该电极用于处理含酚废水和Pb电极进行对比.结果表明,节电33%,转化率达95%,是一种优良的电化学催化剂.
A new kind of non-noble metal anode-Ti/SnO2+Sb2O3+MnO2/PbO2 was studied by means of SEM and XRD. The lifetime and kinetic parameters were determined in 1mol/L H2SO4. Fractal dimension of electrodes was also discussed. The anode is better than lead for treatment of coking waste water of containing phenol. The results show that conversion rate of phenol is 95.8% and economization on electrity is 33%.
