摘要：
Sodium citrate (Na3C6H5O7) is widely used for food, medicine, chemical industry and many other fields due to its excellent performance. The extensive application has resulted in an increase of sodium citrate in industrial and municipal sewage and it aggravates the eutrophication of the water body. In this study, sodium citrate is applied as substrate for the anode electricigens and with which microbial fuel cell (MFC) represents good electricity generation performance. The results show that Na3C6H5O7-MFC achieves a maximum power density of 742.96 mW•m-2, which is 1.77 and 1.12 times of that of sodium acetate (NaAc-MFC) and glucose (Glu-MFC), respectively. The start-up time of NaAc-MFC and Glu-MFC are about 1.8 and 2.9 times of that of Na3C6H5O7-MFC (57 h). The Coulombic efficiency of Na3C6H5O7-MFC is 61.31%, which is obviously superior to NaAc-MFC and Glu-MFC. This indicates that MFC can degrade sodium citrate in wastewater effectively, which provides a possibility of sodium citrate alone as substrate for MFC research. © All Right Reserved.
