Effect on denitrification and electricity generation in microbial fuel cells (MFC) by poly-neutral red modified electrode(聚中性红修饰电极对微生物燃料电池(MFC)脱氮产电性能的影响)
利用电聚合方法制备了聚中性红修饰电极,通过扫描电子显微镜(SEM)、能谱仪(EDS)、傅里叶变换红外光谱(FTIR) 等表征手段对电极材料的微观结构与组成进行研究。为进一步考察聚中性红修饰电极对微生物燃料电池(MFC) 脱氮产电性能的影响,构建了各种不同微生物燃料电池。实验表明,聚中性红修饰阴极微生物燃料电池(CPNR-MFC) 具有最强的脱氮和产电性能,其次为聚中性红修饰阳极微生物燃料电池(APNRMFC) 。在不同进水硝氮浓度下,实验组MFCs 对硝氮的去除率均达到90% 以上,CPNR-MFC 具有0.040 kg ·m-3·d-1 的最大硝氮去除速率和15.29 W·m-3 的最大功率...
