Separator between anode and cathode is an essential part of the microbial fuel cell （MFC） and its property could significantly influence the system perfor- mance. In this study we used polyvinyl alcohol （PVA） polymer membrane crosslinked with sulfosuccinic acid （SSA） as a new separator for the MFC. The highest power density of 7594-4 mW-m-2 was obtained when MFC using the PVA membrane crosslinked with 15% of SSA due to its desirable proton conductivity （5.16 x 10-2 ***）. The power density significantly increased to 11064- 30 mW.m-2 with a separator-electrode-assembly config- uration, which was comparable with glass fiber （11704- 46 mW.m-2）. The coulombic efficiencies of the MFCs with crosslinked PVA membranes ranged from 36.3% to 45.7% at a fix external resistance of lO00f2. The crosslinked PVA membrane could be a promising alter- native to separator materials for constructing practical MFC system.

In this study, DOW CORNING 1-2577 Con- formal Coating was proposed for the cathode diffusion layer of the microbial fuel cell （MFC）. In MFCs, stainless steel mesh cathodes using DOW CORN1NG 1-2577 Conformal Coating/carbon as the diffusion layer and two poly （dimethylsiloxane）（PDMS）/carbon diffusion layers and carbon cloth cathode with four poly （tetrafluoroethy- lene）（PTFE） diffusion layers were constructed for comparison. Under the same operational condition, the MFCs with the DOW CORNING 1-2577 Conformal Coating/carbon diffusion layer produced the maximum power density of 1585q-52mW-m2, compared with those using poly （tetrafluoroethylene）（PTFE） diffusion layers （1421 ~45 mW. m-2） and poly （dimethylsiloxane）（PDMS）/carbon diffusion layers （13534-49 mW. m-E）. The DOW CORNING 1-2577 Conformal Coating could be an alternative for the diffusion layer construction in the MFC due to its remarkable performance and much simple construction procedure.

As the bioelectrochemical system, the microbial fuel cell （MFC） and the microbial electrolysis cell （MEC） were developed to selectively recover Cu^2＋ and Ni^2＋ ions from wastewater. The wastewater was treated in the cathode chambers of the system, in which Cu^2＋ and Ni^2＋ ions were removed by using the MFC and the MEC, respectively. At an initial Cu^2＋ concentration of 500 mg· L^-1, removal efficiencies of Cu^2＋ increased from 97.0%±1.8% to 99.0%±0.3% with the initial Ni^2＋ concentrations from 250 to 1000 mg· L^-1, and maximum power densities increased from 3.1±0.5 to 5.4±0.6W.m-3. The Ni^2＋ removal mass in the MEC increased from 6.84-0.2 to 20.54-1.5 mg with the increase of Ni^2＋ concentrations. At an initial Ni^2＋ concentration of 500 mg· L^-1, Cu^2＋ removal etticiencies decreased from 99.1%±0.3% to 74.2%±3.8% with the initial Cu^2＋ concentrations from 250 to 1000 mg -L1, and maximum power densities increased from 3.0±0.1 to 6.3±1.2W.m^-3. Subsequently, the Ni^2＋ removal efficiencies decreased from 96.9%-4-3.1% to 73.3%4-5.4%. The results clearly demonstrated the feasibility of selective recovery of Cu2~ and Ni2~ from the wastewater using the bioelectrochemical system.

The aim of this study was to synthesize a novel lanthanum(La)doped catalyst and to investigate antipyrine removal in wastewater using the Fenton-like process with the *** La-doped Co-Cu-Fe catalyst was synthesized using the modified hydrothermal *** showed that the Ladoped catalyst had higher specific surface area and lower particle size than the catalyst without La doping(i.e.,the control)(267 vs.163 m2/g and 14 vs.32 nm,respectively).Under the conditions of catalyst dosage 0.5 g/L,H2O2 concentration 1.70 g/L,and NaHCO3 0.1g/L,the antipyrine removal within 60 min using the Fenton-like process with the La-doped catalyst was much higher than that with the control(95%vs.54%).The hydroxyl radical concentration with the La-doped catalyst within 60 min was two times higher than that with the control(49.2 vs.22.1 gg/L).The high catalytic activity of La-doped catalyst was mainly attributed to its high specific surface area based on the X-ray photoelectron spectroscopy *** La-doped catalyst should have great potential to remove antipyrine in wastewater using the heterogeneous Fenton-like process.
