Bioaccumulation of persistent organic pollutants (POPs) is of great concern due to their potentially harmful effects in humans and the environment. The term POPs comprises a variety of chemicals particularly halogenated organics e.g. perfluorinated tensides (PFT), x-ray contrast agents, pesticides and disinfectants, all of which are resistant to photolytic, chemical and biological degradation. Thus removal by conventional wastewater treatment plants is impossible.


The goal of the project „ElektroDeHalo“ is the development of an electrochemical process for degradation of persistent organic pollutants in wastewater. In cooperation with the DWI their recently developed microtubular gas diffusion electrodes, made out of carbon nanotubes (CNT), will be combined with boron doped diamond electrodes (BDD). The microtubes are highly capable to adsorb pollutants due to their high surface area. Subsequently the pollutants are electrochemically desorbed and degraded which leads to the regeneration of the adsorber. To achieve high efficiencies for the degradation process, oxidizing agents are produced at the anode and cathode simultaneously.
