Electro-catalytic oxidation of phenol with Ti-base lead dioxide electrode

The Ti-base PbO2 electrode prepared by electrodeposition of PbO2 on the surface of titanium was used for electro-catalytic oxidation of phenol in waste water. The experimental results show that the electrodeposition of PbO2 at a higher current density for a short time, then followed by a lower current density can get a compact and combinative PbO2 layer. The properties of a Ti/PbO2 electrode with an interlayer of oxide are the best. When this kind of electrode is used to treat phenol containing waste water, the phenol-removal rate is higher and the slot voltage is lower. In addition, by using the phenol-removal rate as an index, the influences of electrolysis current density, mass transfer condition and pH were studied and the optimal condition was confirmed.
