Abstract
The cathodic reducing reactions of active chlorine on 316L SS electrode surface have been investigated by electrochemical techniques. The open circuit potential shifted positively and the limited diffusion current density increased significantly with the increasing content of active chlorine in the 3.5%sodium chloride solution. The two cathodic reduction processes of HClO and ClO- exhibited on the surface of electrode with the active chlorine added to the 3.5%sodium chloride solution and the corresponding potentials of the two reducing reactions were confirmed. The linear relationship of the mass transport_limited Faradaic current, Id vs. the square root of the angular velocity of the rotating disc following indicates that the overall active chlorine reducing reactions is controlled by a mass transport control process.
