Abstract
The mercury content of electrolysis cell brine sludge is reduced by sequentially: (1) acidifying the sludge to a pH below 2.5 and (2) leaching the sludge with aqueous hypochlorite solvent. The mercury content removed from the sludge may optionally be isolated from the solvent and reused as mercury cathode for brine electrolysis.
