【摘要】：微生物燃料电池(Microbial fuel cell,MFC)利用微生物整体作为催化剂催化底物将化学能直接转化为电能,是一种极具应用前景的生物电化学技术。微生物在阳极氧化还原有机物产生电子并传递给阳极,电子通过外电路传递至阴极后将电子释放给阴极中的氧化剂,从而产生电流。当有毒物质进入MFC,微生物活性降低,电子传递量变少,电流降低,而电流的产生与微生物活性呈线性关系,据此可检测样品的毒性。本文主要介绍了微生物燃料电池在毒性物质抗生素、重金属离子、有机污染物、酸等方面的研究,并分析了微生物燃料电池存在的问题及未来研究方向,以期不久的将来微生物燃料电池能付之使用。
[Abstract]:Microbial fuel cell (MFCs) is a promising bioelectrochemical technology, which uses microorganism as a catalyst to catalyze the direct conversion of chemical energy to electrical energy. The microorganism produces electrons in anodic redox organic matter and transfers them to the anode. The electrons are transferred to the cathode through the external circuit and then released to the oxidant in the cathode to produce the current. When the toxic substance enters into MFC, the microbial activity decreases, the electron transfer quantity decreases, and the current decreases, and the generation of the current is linearly related to the microbial activity, according to which the toxicity of the sample can be detected. This paper mainly introduces the research of microbial fuel cell in the aspects of antibiotic, heavy metal ion, organic pollutant, acid and so on, and analyzes the existing problems and future research direction of microbial fuel cell. It is hoped that microbial fuel cells will be used in the near future.
