REMOVAL OF TRACE HEAVY METALCONTAMINANTS FROM ALGAE ANDTHE CARRAGEENAN CONTAINED THEREINAbstract of the DisclosureHeavy metal contaminants which are normally presentin trace amounts are removed from those algae of the generaGigartina and Iridaea which contain a major amount of lambdatype or non-gel-forming carrageenan and from the carrageenanitself by soaking the algae in a solution containing a water-soluble potassium salt which does not cause appreciable ex-traction of the carrageenan from the algae.
