Typical Properties and Applications

DOWEX C-75 NG (H) is a macroporous strong acid cation exchange resin with excellent physical and chemical stability. It is supplied with a minimum of 99.7% of ionic sites in the H⁺ form and a low level of impurities. This resin exhibits outstanding selectivity for Cs and Co isotopes, resulting in high decontamination factors for these species. It is available as a mixed bed resin with DOWEX SBR LC NG (OH) anion exchange resin, sold as DOWEX MR-72 LC NG.

Packaging

• 50 liter or 5 cubic foot drums
