Electrochemical oxidation of sulfide is a promising method for its removal from wastewaters. One of the primary product of electrochemical oxidation is elemental sulfur. Sulfur deposits on the electrode and deactivates it. In this paper electrochemical removal of aqueous sulfide in water was investigated. Two electrolytes were employed in the undivided cell, and results showed that pH of the electrolyte is an important parameter in the removal of sulfide. The results of this study showed that adsorption of sulfide in sodium hydroxide electrolyte is proper than the basic electrolyte. The optimum sulfide adsorption potential for 400 ppm sulfide in sodium hydroxide was determined -0.65 V.
