Abstract/OtherAbstract:
|
Pentachlorophenol (PCP) was more rapidly degraded in acetate and glucose-fed microbial fuel cells (MFCs) than in open circuit controls, with removal rates of 0.12±0.01mg/Lh (14.8±1.0mg/g-VSS-h) in acetate-fed, and 0.08±0.01mg/Lh (6.9±0.8mg/g-VSS-h) in glucose-fed MFCs, at an initial PCP concentration of 15mg/L. A PCP of 15mg/L had no effect on power generation from acetate but power production was decreased with glucose. Coulombic balances indicate the predominant product was electricity (16.1±0.3%) in PCP-acetate MFCs, and lactate (19.8±3.3%) in PCP-glucose MFCs. Current generation accelerated the removal of PCP and co-substrates, as well as the degradation products in both PCP-acetate and PCP-glucose reactors. While 2,3,4,5-tetrachlorophenol was present in both reactors, tetrachlorohydroquinone was only found in PCP-acetate MFCs. These results demonstrate PCP degradation and power production were affected by current generation and the type of electron donor provided. |
