Efficient Reduction

Cr(VI) was reduced at a carbon felt cathode in an air-cathode dual-chamber microbial fuel cell (MFC). The reduction of Cr(VI) was proven to be strongly associated with the electrogenerated H2O2 at the cathode. At pH 3.0, only 27.3% of Cr(VI) was reduced after 12h in the nitrogen-bubbling-cathode MFC, while complete reduction of Cr(VI) was achieved after 6h in the air-bubbling-cathode MFC in which the reduction of oxygen to H2O2was confirmed. The results showed that the efficient reduction of Cr(VI) could be achieved with an air-bubbling-cathode MFC.
