High rate copper and energy recovery in microbial fuel cells

摘要: Bioelectrochemical Systems (BESs) are a novel, promising technology for the recovery of metals. The prerequisite upscaling from laboratory to industrial size is that high current and power densities can be produced. In this study we report copper sulfate stream (2 g L-1 Cu2+) using scale BES at rate. To achieve this, used novel cell configuration reduce internal voltage losses system. At anode, electroactive microorganisms produce electrons surface an electrode, which generates stable 485 mV when combined with cathode where reduced. system, maximum density 23 Am-2 in combination 5.5 Wm-2 was XRD analysis confirmed 99% purity deposited onto surface. . Analysis showed highest current, most occurred membrane, while anode had lowest contribution total loss. These results encourage further development BESs bioelectrochemical metal recovery.
