This research aimed to develop electrodes that have high resistance to corrosion, low electrochemical activity, ease of manufacturing and economically viable. The experimental work was focused on the development of polymeric electrodes through three different procedures. The first procedure involved the synthesis of copper oxide at the nanometric scale. The second one involved the synthesis of pure copper at the nanometric scale. Finally, the last one used commercial alloys obtained from a mixture of copper and zinc. Their filaments were incorporated into a polymer matrix to obtain the electrodes. The brass wire electrode mixed with epoxy resin presented the best performance due to its high electrical conductivity, low cost, and ease of manufacturing. These polymer electrodes presented good corrosion resistance in aggressive environments, which are caused by pH variation during the electro-drainage process. The experimental setup aimed the comparison of the behavior between the electrode with bass filaments immersed in an epoxy resin matrix and copper electrodes. The comparison has shown that copper electrodes undergo rapid corrosion with higher rate of mass loss generating oxides. These oxides are deposited on the surface of the electrode reducing its electrical conduction capacity. On the other hand, the electrodes developed in the present study showed a low loss of mass. In relation to energy consumption during the electro-drainage process, it was observed that the tests with copper electrodes present higher energy demand than the developed electrodes.
