Abstract: Disturbances occurring in chloride-caustic cells using the amalgam method are caused by felty coatings which form on the bottom of the cells. These disturbances can be avoided by treating the mercury (after it has left the decomposer and before or after it has entered the electrolytic cell) with an aqueous solution which contains chlorine and/or ferric chloride.
