摘要
为提高普通PbO2电极的性能,以电沉积法制备了分别掺杂Fe,Co,Ni的钛基PbO2新型改性电极,优化并确定了电极的制备工艺;以对硝基苯酚为目标污染物,考察了电极的电催化氧化性能;探讨了对硝基苯酚的降解动力学,其降解符合表观拟一级反应动力学关系.分析结果表明:掺杂Fe,Co,Ni的改性电极的电催化性能优于普通钛基PbO2电极,且掺铁电极催化性能最高,降解1 h对硝基苯酚的去除率为84%,处理成本比普通钛基PbO2电极的成本降低1/3,有较好的环保应用前景.
Novel doped PbO_2/Ti electrodes were produced by electro-deposition in acid solution.Taking p-NP as model pollutant,the electro-catalytic characteristics of prepared anodes were investigated.Results showed that the p-NP degradation was more efficiently carried out on doped PbO_2/Ti anodes than that on traditional PbO_2/Ti.Fe-doped PbO_2/Ti had the highest electro-catalytic characteristics,and reduced thirty-percent price of treatment.The removal of p-NP is 84% in one hour.At present study of p-NP was proposed,which should be fit for the first order reaction model.
