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.
