the cell should be operated at high temperature. The maximum current density might be a function of the Reynolds number as well as the operating temperature. Therefore, it should be investigated further, for de-velopment and scale-up of this process, from a chem-ical engineering point of view. Conclusion An electrochemical process for recovery of chlorine from waste gas has been developed. Fundamental studies on this process, emphasizing the cathodic reac-tion, have been made. Since the l imiting current density for dissolved chlorine is small, the rate of the over-all cathodic process is almost controlled by the diffusion current for cupric chloride in the electrolyte. The higher the concentration and the temperature, the larger the current density obtained. The flow velocity of the electrolyte near the working cathode is also an important factor because the cathode reac-tion is controlled by diffusion (7)
