چکیده انگلیسی
The effects of different electron donors and electron acceptors on the performance of microbial fuel cell (MFC) were investigated. In the ClO4â system, the optimum electron donor and initial perchlorate (ClO4â) concentration were acetate and 150Â mg/L, respectively. In the ClO4ââNO3â and ClO4ââClO3â systems, the perchlorate reduction rates were retarded and the lag time was increased with increasing concentrations of nitrate and chlorate; the output voltage increased when nitrate was reduced, and the output voltage decreased when chlorate was reduced. In the ClO4ââSO42â systems, the perchlorate reduction rates and output voltages did not dramatically decrease until the sulfate (SO42â) concentration increased to 600Â mg/L. Thermodynamic and electrochemical analyses were used to explain the difference in the reduction orders of multiple electron acceptors and responses of the anode activity. The microbial analysis showed that the electron acceptors did not change the composition of the anodic microbial community. The dominant species were responsible for the enhancement of the higher perchlorate reduction rate and the higher output voltage.
