焦化含酚废水在Ti／PbO2电极上的氧化处理

Oxidizing Treatment of Coking Waste Water of Containing Phenol with Ti/ PbO_2 Electrode

摘要:

通过对Ｔｉ／ＳｎＯ２＋Ｓｂ２Ｏ３＋ＭｎＯ２／ＮＯ２阳极在Ｈ２ＳＯ４中的使用寿命和电化学动力学参数的测试，并把该电极用于氧化处理焦化含酚废水，且和铅电极进行了比较研究，结果表明：Ｔｉ／ＳｎＯ２＋Ｓｂ２Ｏ３十ＭｎＯ２／ＰｂＯ２电极在Ｈ２ＳＯ４中具有较长的使用寿命，能使酚的转化率达到９５％并较Ｐｂ电极节电３３％，是一种优良的电化学催化剂。

Abstract:

Ti / SnO2+Sb2O3+MnO2 / PbO2 anode has been studied by means of SEM and XRD. The lifetime and electro chemical kinematic parameter of electrod were determined. The anode is better than lead for treatment of coking waste water of containing phenol. The results show that the anode is a better electrocatalyst in sulfuric acid.
