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