Abstract:

The deoxidizing packing material (DPM) in a microbial fuel cell (MFC) was improved by adding a deoxidizing agent (DA) to its surface to form DPMDA-out, causing the DA effectively to consume dissolved oxygen in the anode tank. The removal efficiencies by MFC using DPMDA-out of isopropanol and styrene were 8.72–30.5 % and 2.50–15.7 % greater than the removal efficiencies by adding DA to the interior of the DPM to form DPMDA-in, respectively. This results suggest that MFC processes hydrophilic isopropanol more easily than hydrophobic styrene. The maximum voltage outputs of a DPMDA-out-based MFC for isopropanol and styrene are 1.08 and 1.16 times those of a DPMDA-in-based MFC and the power densities are 1.31 and 1.57 times as large, respectively. Even though the removal efficiency of styrene (15.7 %) in the modified MFC is less than that of isopropanol (30.5 %), the electricity production by the MFC with styrene as its substrate exceeds that by the MFC with isopropanol. A kinetic analysis revealed that the effectiveness of improving the anode material was more easily reflected by the reaction rate constant (k) of isopropanol. The improved DPMDA-out enhances the removal efficiency of targeted pollutants and the production of power by the MFC.
