Abstract
A method of producing treated ion exchange resin material includes exposing an enclosed vessel containing ion exchange resin and a pre-treatment solution to high energy radiation. The treated ion exchange resin material has reduced organic impurities or total organic carbon (TOC).
Claims11
A method of producing a treated ion exchange resin material, comprising:
- providing ion exchange resin having of organic impurities in a vessel comprising a pre-treatment solution and a void space;
- and
- exposing the ion exchange resin, the pre-treatment solution, and the void space within the vessel to high energy radiation to produce a treated ion exchange resin material having reduced organic impurities and a treated void space having reduced volatile organic species.
