In this study, the performance of carbon cloth (CC) modified with iodine (I₂) doped polythiophene nanoparticles (PTh-NP) as an anode was investigated in a double chamber microbial fuel cell (MFC) for the purpose of simultaneous power generation and lead (Pb²⁺) removal using Shewanella putrefaciens as the biocatalyst. The CC with I₂ doped PTh-NP displayed good electrochemical characteristics compared to pristine CC and the CC with undoped PTh-NP. A further increase in the electrical conductivity using the modified CC with biofilm was observed, which matured after 51 h, as evident from cyclic voltametry. The removal of lead for concentrations, viz., 20 ppm, 30 ppm, and 40 ppm, was analyzed. The optimum concentration was found to be 30 ppm with a maximum power density of 0.84 W/m² and a current density of 1.45 A/m² at an optimum resistance of 250 ohms. At the end of the process, total organic carbon (TOC) and Pb²⁺ removal of 95.1% and 89.6%, respectively, were obtained at the optimum concentration. Hence, this study demonstrates the possibility of utilizing MFC for treating low concentrated metal wastewater.

在这项研究中，以双室微生物燃料电池（MFC）为研究对象，研究了用碘（I ₂）掺杂的聚噻吩纳米颗粒（PTh-NP ）改性的碳布（CC）的性能。使用腐臭希瓦氏菌作为生物催化剂去除铅（Pb ²⁺）。CC与我₂与原始CC和未掺杂PTh-NP的CC相比，掺杂PTh-NP的电化学性能良好。从循环伏安法可以明显看出，使用带有生物膜的改性CC可以进一步提高电导率，并在51小时后成熟。分析了浓度为20 ppm，30 ppm和40 ppm的铅的去除情况。发现最佳浓度为30 ppm，在250欧姆的最佳电阻下，最大功率密度为0.84 W / m ²，电流密度为1.45 A / m ²。在该过程结束时，总有机碳（TOC）和Pb ²⁺在最佳浓度下，分别去除了95.1％和89.6％。因此，这项研究证明了利用MFC处理低浓度金属废水的可能性。
