采用阳极恒电流电沉积技术在0.30mol/L、pH=1~2的Pb(NO3)2溶液中制备不锈钢基PbO2电极.采用X射线衍射、扫描电镜技术对电极的结构及表面形貌进行了表征和分析.对不锈铜基PbO2电极电催化氧化活性酚类模拟废水的去除率进行了研究,结果表明,在50mA/cm。电流密度下降解0.01mol/L酚类模拟废水,80min后测得邻苯二酚的去除率高达93%,苯酚的去除率达80%以上.
PbO2 electrode on stainless steel substrate was fabricated by anodic galvanostatic electrodeposition technique in 0.30 mol/L and pH = 1 - 2 Pb ( NO3 ) 2 aqueous solution. The structure and surface morphology of electrode was characterized and analyzed by X-ray diffraction and scanning electron microscopy. The removal rate of re- active phenols simulating waste water was studied by electro-catalytic oxidation method with the PbO2 electrode on stainless steel substrate. The result showed that when the phenols simulating waste water with initial concentration about 0.01 mol/L, the removal rate for o-dihydroxybenzene could reach 93% and phenol could reach more than 80% under 50 mA/cm2 degradable current density for 80min.
