摘要
采用 Ti O2 薄膜光电催化法 ,借助于 HPLC测试技术研究了苯酚的降解及氧化产物的分布。研究结果表明 ,苯酚的降解以及中间产物的分布与苯酚的外加电压、Ti O2 薄膜电极的制膜条件、样品处理量等因素有关 ,在适当的光电催化条件下 ,可以将苯酚全部分解为无毒无害的低分子化合物。
The photoelectrocatalytic destruction of phenol was studied and the concentrations of phenol as well as phenolic intermediates were detected using HPLC technique. The results showed that the external potential,TiO 2 thin film and sample volume had effect on the destruction of phenol and the distribution of its intermediates. Under favourable photoelectrocatalytic conditions,the phenol can be destructed completely.
