Szilard-Chalmers Reaction of the Trioxalatochromium Ion Adsorbed on an Anion-Exchange Resin under Continuous Elution Conditions

Abstract

Summary A flow method during reactor irradiation to separate the recoiling species from the parent complex ion adsorbed on an ion-exchange resin was applied to the trioxalatochromium ion. The separable yield increased as expected: 80% for the dynamic method compared with 66% for the static method, at p H 2.0 by HNO3. The yield decreased with increasing pH with nitric or acetic acid as eluent, but the oxalic acid case showed a reverse trend. The specific activity increased with increasing p H in all cases.
