The arsenite removal from the simulated groundwater was studied by the plate graphite electrode electric adsorption. We investigated that the effects of the ionic strength, the initial arsenite concentration, the distances between the two plate electrode, and the voltage on the arsenite removal efficiency. The experimental results showed the arsenite removal efficiency reached up to 99.4% by the graphite electrode when the ionic strength is 0.1 mol/L NaCl, the voltage is 2.5 V, the distances between the two plate electrode is 3 cm, the electric adsorption time is 60 min. The water quality after electric adsorption approximates national standard of drinking water. The arsenite removal was 98.4%?99.2% in the 8 cycles of electrosorption/electrodesorption of arsenic, furthermore, the graphite electrode showed the higher performance after the regeneration.
