TiO2纳米管修饰电极处理反渗透浓水研究

摘要

The novel TiO2 nanotubes modified electrode was obtained for electrochemical oxidation of reverse osmosis concentrate. Scanning electron microscope (SEM) and linear polarization curves were characterized for the electrode. The influences of electrolysis time, current density and pH on electrochemical oxidation of reverse osmosis concentrate were studied. The removal of different organic fraction of reverse osmosis concentrate by electrode was also discussed. The results showed that the TiO2 nanotubes modified electrode had high electrochemical performance for the treatment of reverse osmosis concentrate.%研制了新型的TiO2纳米管修饰电极，应用于反渗透膜浓水的电化学氧化处理；利用扫描电镜和线性极化曲线对电极进行了表征；考察了电解时间、电流密度和pH值因素对电化学氧化处理反渗透膜浓水的影响；并分析了电极对反渗透浓水中各有机物组分的去除效果。实验结果表明TiO2纳米管修饰电极对反渗透浓水具有较高的电催化性能。
