Process for extracting ferric iron from an aqueous solution

摘要

Ferric iron is removed from an aqueous chloride solution containing other cations by extracting ferric iron with a liquid organic extractant comprising a ketone having less than about eight carbon atoms for a sufficient period of time to extract ferric iron into the organic liquid extractant. The organic liquid extractant is separated from the aqueous chloride solution containing other cations and the ferric iron is stripped from the organic liquid.
