Compared to Two Kinds of Methods for the Degradation of an Anthraquinone Dye Reactive Brilliant Blue KN-R

Abstract:

Taking anthraquinone dye reactive brilliant blue KN-R as a target pollutant, this paper studied KN-R degradation rates and electric generation performances in the system of Fe²⁺/PDS and Fe²⁺/PDS-MFC. The Fe²⁺/PDS system is that persulfate (PDS) is activated by ferrous iron (Fe²⁺) ,while Fe²⁺/PDS-MFC system is using Fe²⁺/PDS system as the cathode of microbial fuel cells (MFC) .The results showed that in the two systems, the KN-R degradation rate was increased and then decreased with the increase of initial Fe²⁺ dosage. With the increase of pH, the KN-R degradation rapid declines. In the two systems, both of the KN-R degradation reaction was divided into two stages. In addition, the process of reaction conforms to the first-order kinetic equation. Compared with Fe²⁺/PDS system, the Fe²⁺/PDS-MFC system’s ability to degrade pollutants have little change, the main advantage of Fe²⁺/PDS-MFC system is able to obtain higher and more stable power. Under an optimal condition, the maximum power density achieved 294.07 mW/m², the KN-R degradation rate was 96.90%.
