Process for removing heavy metal ions with a chelating cation exchange resin

摘要

The invention is for a process of removal of dissolved heavy metal cation contaminants from an organic solution. The process of the invention involves providing a chelating ion exchange resin modified by removal of sodium ions therefrom and contacting said organic solution with said modified exchange resin for a time sufficient to remove ionic metal impurities. The invention is useful for removal of ionic contaminants from organic solutions requiring high purity.
