The function of mercury in this process is to serve as the
cathode of the electrolysis cell. A flowing film of mercury
forms an amalgam with sodium metal, which is released from
the brine solution at the cathode during electrolysis. Losses of mercury from plants ranged from 150 ? 250g for 1000kg of chlorine produced. The amount of chlorine produced by this method has been steadily increasing since about 1947. |
