六价铬(Cr(VI)是一种剧毒、致癌的金属铬，可通过对工业废水的不当处理而进入环境。对铬(VI)的去除研究旨在产生一种可持续的方法，将铬(VI)有效地还原为铬(III)。微生物燃料电池(MFCs)是一种利用生物质废弃物的可持续能源驱动的绿色环保技术，是一种理想的铬(VI)减量化技术。MFC性能的优化需要了解MFC的工作原理。因此，本文综述了利用普通微生物燃料电池系统、植物微生物燃料电池系统、土壤微生物燃料电池系统和混合微生物燃料电池系统减少废水中六价铬的研究进展。此外，还讨论了影响铬(VI)还原效率的因素，即废水的浓度和组成、有机基质、电极性能、电解液的pH值和温度、曝气效果(含氧量)、膜/分离器的稳定性和微生物。最后，本综述将概述大规模发展双室MFC的挑战、未来前景和战略。
Hexavalent chromium (Cr(VI) is a highly toxic and carcinogenic form of chromium (Cr) metal and can enter the environment through improper treatment of industrial wastewater. Investigations on the removal of Cr(VI) aims to produce a sustainable method to efficiently reduce Cr(VI) to Cr(III). Microbial fuel cells (MFCs) is a green technology driven by sustainable energy from biomass waste, which is ideal for the reduction of Cr(VI). Optimization of the MFC performance requires an understanding on the working principles of MFC. Therefore, this article provides a comprehensive review of Cr(VI) reduction in wastewater using the general MFC system, the plant microbial fuel cell (PMFC) system, the soil microbial fuel cell (sMFC) system, and hybrid MFC systems. In addition, factors that influences the efficiency of Cr(VI) reduction, namely the concentration and composition of wastewater, the organic substrates, the properties of the electrodes, the pH and the temperature of the electrolytes, the effect of aeration (oxygen content), the stability of the membrane/separator and, the microorganisms will be discussed. Finally, this review will outline challenges, future prospects, and strategies for a largescale development of double-chamber MFCs.
