Abstract The removal of carbamazepine (CBZ) in drinking water by electrochemical coupled membrane process was investigated. The effects of voltage, initial CBZ concentration, ionic strength, and humic acid on the removal efficiency of CBZ were systemically investigated. The removal efficiency of CBZ gradually increased with the increase of applied voltage, and the optimal removal efficiency of CBZ was obtained with 2V applied voltage. When the initial CBZ concentration were in the range of 50~500μg/L, the removal efficiencies of CBZ by electrochemical coupled membrane process were above 85% by applying 2V voltage. However, the removal of CBZ could be inhibited by the increase of ionic strength and humic acid concentration due to the competitive effect of ·OH in the system. Compared with powdered activated carbon/microfiltration (PAC/MF) process, the removal efficiency of electrochemical coupled membrane process was more stable and the cost was lower.
