The problem of wastewater has long been ubiquitous and has great consequences for the environment and its
inhabitants. Microbial fuel cells (MFCs) have enormous potential for the treatment of wastewaters polluted with
azo dyes. The amount of energy that can be produced from a single-chamber MFC is sufficient to perform
decolorization and degradation of such dyes, which are widely used in the textile industry. This study on the azo
dye, reactive black 5 (RB5), provides an alternative method through three parallel-connected MFCs to obtain
electricity that directly serves for the dye’s electrochemical degradation. We examined degradation followed by
decolorization of RB5 using Fe and Pt electrodes, together with H2O2, to achieve the electro-Fenton process. The
amount of voltage produced (295 mV), the current density (276 mA m− 3
) and the power density (50 mW m− 3
)
were sufficient to degrade 25 mg L-1 RB5 dye with 0.5 mM H2O2 in just 2 h. The dye degradation mechanism was
inve...stigated using UV–VIS, FT-IR and HPLC-MS/MS. The ecotoxicity of the degradation products was assessed
using a bacterial model, Aliivibrio fischeri. These tests showed that there was successful degradation of the dye to
products whose toxicity is less than that of RB5.
