제목 Bioelectricity generation with simultaneous recovery of heavy metal ion and rare earth element
초록 Bacteria can transfer their residual electron onto anode electrode electrically connected with cathode electrode in microbial fuel cell (MFC). To decrease the MFC operation cost, metal wastewater is used to apply as the oxidant. We presented simultaneous reduction of heavy metal ions (Cr6+ and In3+) with bioelectricity generation using microbial fuel cell having proton exchange membrane (PEM) or bipolar exchange membrane (BPM) in this study. Over 300 μA of current generation in Cr-MFCs were monitored while less than 100 μA of current generation were identified in In-MFCs. Identification of the precipitated chromium and indium was conducted by XPS, XRD and EDS. The results presented that reduced amorphous precipitations of metal ions were facilitated by electrode electron transference in MFC cathode. As the results, we proposed the possibility of the application of MFC for the production of bioelectricity with removal of useful metal ions from wastewater.
