Abstract:
Electrokinetic remediation is one of the methods for cleaning of soil and sediments (Rozas and Castellote, 2012). In this case, by applying a weak electric field using the external power supply, the pollutants are separated from the soil or sediment by various mechanisms, especially electrical migration. But due to the cost of supplying electricity, it is not affordable(Acar et al., 1995). On the other hand, in the microbial fuel cells, bacteria release electrons by consuming organic matter and producing electric current. Therefore, in this study, microbial fuel cells process with three different electrodes at the anode and combination with granular activated carbon was used to produce green weak electric field. Based on the electrical migration mechanism, the removal rate of hexavalent chromium from marine sediments was evaluated by combining three physical, chemical and biological processes.
