摘要: 微生物燃料电池（Microbial fuel cell，MFC）传感器检测水体毒性灵敏度偏低是阻碍其实际应用的瓶颈之一。本研究利用多壁碳纳米管（MWNT）和导电炭黑（GCB）修饰石墨毡（GF），作为阳极电极启动MFC传感器。考察了碳纳米材料修饰阳极电极对MFC传感器电化学性能及水体毒性检测灵敏度的影响。结果表明，GCB和MWNT修饰的电极比未修饰的电极内阻小，MFC的功率输出由大到小的顺序为：GCB/GF-MFC（2.63 W/m²） > MWNT/GF-MFC（2.56 W/m²） > GF-MFC（2.09 W/m²）。以3，5-二氯苯酚（DCP）作为模型毒物进行毒性检测实验，10 mg/L DCP对3个MFC毒性传感器的平均抑制率为：MWNT/GF-MFC（31.8%） > GCB/GF-MFC（26.3%） > GF-MFC（20.1%），碳纳米材料修饰阳极电极组装MFC的毒性检测灵敏度均有所提高，MWNT/GF-MFC灵敏度最高。本研究对MFC型传感器在水污染预警中的实际应用研究提供了参考。

Abstract: The low sensitivity of microbial fuel cell (MFC)-biosensor is one of the bottlenecks in its practical application. To investigate the effect of anode electrode modified with carbon nanomaterials on the sensitivity of water toxicity detection of MFC-based biosensor, graphite felts (GF) were modified using two carbon nanomaterials of multi-walled carbon nanotubes (MWNT) and conductive carbon black (GCB). MFC biosensors were started up with the anode electrodes, and the results showed that resistance of the GCB and MWNT-modified electrode was smaller than that of unmodified electrode, and the order of MFC power output was GCB/GF-MFC (2.63 W/m²) > MWNT/GF-MFC (2.56 W/m²) > GF-MFC (2.09 W/m²). Then, 3, 5-dichlorophenol poison (DCP) was used as a model toxicant in toxicity test, the order of toxicity inhibition ratios of 10 mg/L DCP to three MFC biosensor was MWNT/GF-MFC (31.8%) > GCB/GF-MFC (26.3%) > GF-MFC (20.1%). The sensitivity for toxicity detection by MFC biosensors with anode electrode modified with carbon nanomaterials was improved, and MWNT/GF-MFC had the highest sensitivity. The result of the study may promote the application of MFC biosensor in water pollution monitoring.
