The soil microbial fuel cell (MFC) is a promising biotechnology for the bioelectricity recovery as well as the remediation soil.
Moreover there were no studies on the heavy metal pollution in a soil MFC yet. A soil MFC was constructed to remediate the
contaminated soil and the electric field was generated from the oxidation of the acetate at the anode. We demonstrated that the copper
migration, the power generation and the pH variation in the soil and the electrodes. The maximal voltage and the power density of
539 mV and 65.77m W/m2 were obtained in the soil MFC. The chemical fractionation of copper (Cu) was analyzed with a modified
BCR sequential extraction method. The soluble Cu form and the total Cu contents from the anode to the cathode increased and the
difference between them kept growing over time. The Cu fractions in the soil and the electrodes were converted with the change of the
dramatic pH from the anode to the cathode. There was a focusing effect leading to the change of the copper forms and the extractable
acid form content increased in the three-fifths where the acid and the alkali fronts met.
