Resumo: In the present study we describe a simple method to immobilize the redox mediator anthraquinone‐2,6‐disulfonate (AQDS) at the surface of graphite electrodes, by means of a commercial anion exchange membrane. Cyclic voltammetry experiments confirmed the efficacy of the immobilization protocol and the long‐term (over 70 days) electrochemical stability of the AQDS‐functionalized electrode. Potentiostatic (–300 mV vs. SHE) batch experiments proved the capability of the electrode in accelerating the bioelectrochemical reductive dechlorination of the groundwater contaminant 1,2‐dichloroethane (1,2‐DCA) to harmless ethene by a mixed microbial culture, by serving as electron donor in the process. Considering the reported broad range of anodic and cathodic reactions catalyzed by AQDS, the herein described functionalized electrode has a remarkable potential for application in the environmental and industrial sector.
