Anion Exchange of 58Elements in Hydrobromic Acid and in Hydriodic Acid.

摘要

Anion exchange distributions of 58elements have been measured from 0.1-8.7M HBr and from 0.1-7.4M HI onto three strong-base resins, 8and 4% cross-linked and macroporous. Data were obtained by 16-to 18-h dynamic batch contacts. Anion exchange in these media is compared to that in HCl. The effect of resin cross-linkage is considerably greater in HI media than in HBr and HCl media. Examples are presented of potentially useful separations using HBr and HI media alone and in combination with HCl. (ERA citation 03:031446)
