| 摘 要： | 在电激励下,电极表面活性点生成的.OH能氧化水溶液中的有机物。本文研究了钛基二氧化铅电极做工作电极催化降解水中苯酚时,支持电解质溶度、温度、电流密度、pH值等因素对酚降解效率的影响。实验得知,在支持电解质CNa2SO4=0.05 mol.L-1、20℃2、0 mA.cm-2、pH=3条件下,电解100 mL 0.005mol.L-1苯酚溶液,120 min内降解了78.62%。紫外光谱分析了200 min内的电解试样,得知苯酚电解过程先生成中间物而后变成CO2和H2O,且降解率为94.35%。

| Abstract: | The hydroxyl radicals produced in the electrode surface can oxidise organics in aqueous solution under the action of electric field.In this paper,Ti-based PbO2 electrode is used as a catalytic electrode,and we analyzed the roles of concentration of electrolyte(Na2SO4),temperature,current density and pH value on the degradation of phenol in aqueous solution with ultraviolet spectrum.The result indicates that in a 100ml of 0.005M phenol aqueous,the concentration of phenol was degraded by 78.62% in 120min unde... |
