CSA 309

Nuclear Grade Strong Acid Cation Exchange Resin

DOSHION CSA 309 is a specifically developed Nuclear Grade GEL Type Strong Acid Cation Exchange Resin product by the sulfonation of styrene-divinylbenzene copolymers. It has a high capacity with excellent physical and chemical properties especially designed to remove radioactive isotopes from aqueous solutions. It is manufactured under the most stringent quality controls. DOSHION CSA 309 is a factory regenerated resin, ready to use application for the nuclear industry. The resin is supplied primarily in H+ form.
