Nickel(II) removal from wastewater by Microbial Fuel Cell

The effect of the high standard electrode potential of copper ions on the anode of microbial fuel cells was demonstrated in a previous study. This paper studied the effect of the low standard electrode potential of nickel ions on the anode, including removal efficiency, migration and distribution. More than 95% of the nickel can be removed in the anode of MFCs (Microbial fuel cells) with influent feed to the anolyte containing Ni2+, while the removal mechanism of nickel ions was chemical precipitation, including approximately 75.5% in the anode and approximately 15% in the cathode.
