In this study, the coal-based tubular carbon membrane was selected as the electrode of electrically switched ion exchange, and Pb2+ in dilute solution was separated by electric double layer and electrically switched ion exchange mechanism. At the same time, the electrically switched separation performance of Pb2+ was investigated under different operating mode(static and dynamic), electrode potential, initial concentration of Pb2+ and coexisting cations. The results show that carbon membrane, as a graphitized porous carbon material, exhibited excellent electroactivity. The efficient separation of Pb2+ was achieved by the electric double layer effect of carbon membrane electrode surface and ions and the complexation of oxygen-containing functional groups under negative potential. When dynamic permeability condition was applied Pb2+ could not be detected in the receiver cell all the time under-5 V potential. Even in the coexistant cation solution, the removal efficiency of Pb2+ maintained approximately 100%. In addition, after five times of adsorption and desorption cycle, carbon membrane still had 96% removal efficiency, showing good regeneration performance and stability.
