  • Process for removing mercury from brine sludges
    Patent number: 4124459
    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.

  • Removal of trace heavy metal contaminants from algae and the carrageenan contained therein
    Patent number: 4112223
    Abstract: Heavy metal contaminants which are normally present in trace amounts are removed from those algae of the genera Gigartina and Iridaea which contain a major amount of lambda type or non-gel-forming carrageenan and from the carrageenan itself by soaking the algae in a solution containing a water-soluble potassium salt which does not cause appreciable extraction of the carrageenan from the algae.
