An investigation of the applicability of the new ion exchange resin, Reillex{trademark}-HPQ, in ATW separations. Milestone 4, Final report

Abstract

The investigations with the anion exchange resin Reillex_-HPQ is continuing along several different paths. The topics of current investigations that are reported here are: 1. The sorption behavior of chromium(VI) on ReillexTM-HpQ from nitric acid solutions and from sodium hydroxide/sodium nitrate solutions. 2. The sorption behavior of F-on ReillexTM-HpQ resin in acidic sodium nitrate solution. 3. The sorption behavior of C1-on ReillexTM-HpQ resin in acidic sodium nitrate solution. 4. The sorption behavior of Br-on Reillex_-HPQ resin in acidic sodium nitrate solution.

An investigation of the applicability of the new Reillex{trademark}-HPQ anion exchange resin system for technetium/rhenium and uranium in the Hanford waste tanks. Milestone 4 final report

“…The characterization of the interaction of this resin with Reo, and TcO, has been investigated and reported. [6][7][8][9] We have found that the behavior of the resin ReillexTM-HPQ with Reo, is very close to that with TcOZ. Hence, the characterization of the behavior of a different resin with Reo; should closely approximate that with TcOZ.…”
