Abstract Scope |
This study develops a three-chamber photosynthetic algae microbial fuel cell (TCAC-MFC) engaged Chlorella sp. as cathode to generate O2 and produce alkalinity for simultaneously Pb(II) precipitation in the cathode chamber and power generation for the developed system. The performance of the system was evaluated by optimizing the biocathode and operation factors including initial pH and DO concentration. The optimum bio-cathode of TCAC-MFC was found using algae pre-cultured in high phosphorus medium, with initial pH of 8.33 and DO of 7 mg L-1. The maximum power density of 835 mW m−2 was achieved. The long-term run of Pb(II) removal and electricity generation under the optimum cathode was further conducted and achieved a stable Pb removal of around 100% and the maximum power density of around 804 mW m−2. The stable nontoxic Pb(OH)2, PbO, PbCO3 and (PbCO3)2Pb(OH)2 are the main component after Pb(II). |
