摘要
采用电沉积法制备聚乙二醇(PEG)改性新型不锈钢基PbO2电极,通过线性极化扫描(VA)表征改性PbO2电极电化学性能,并分别从电流密度、废水初始pH、温度等因素考察电极对甲基橙模拟废水的降解。结果表明,PEG改性PbO2电极具有更高的析氧电位,降解甲基橙的最佳条件为电流密度50 mA/cm2,废水初始pH为6,温度为20℃。
PbO2 electrodes modified with polyethylene glycol （PEG） were prepared by electrodeposition, linear sweep voltammetry （VA） were carried out to get a better understanding of its electrochemical properties, And separately from the current density, initial water pH, temperature and other factors investigated electrode on the degradation of methyl orange simulated wastewater. The results showed that PEG modified PbO2 electrode had a higher oxygen evolution potential, the optimal conditions for degradation ofmethyl orange for the current density was 50 mA/cm2, wastewaterinitial was pH 6, the temperature was 20℃.
