Rapid Chemical Separation for Bk

Abstract

An anion exchange in mineral acid and methanol system was examined in view of rapid chemical separation. An elution behavior of Bk in hydrochloric acid-methanol system was obtained using ²⁵⁰Bk. An elution behavior of Bk in nitric acid-methanol system was predicted from the relationship between an elution position and an ionic radius . The separation was completed for nitric acid-methanol system and for hydrochloric-methanol system within 40 and 25 min, respectively.
