摘要

利用192 Ir放射性示踪研究了铱在AG1-X8阴离子树脂上的吸附解吸行为。首先用氯气对样品溶液中铱的化学种态进行调整

然后对吸附在树脂上的铱用抗坏血酸还原

最后用HClO4与HCl混合液洗脱。实验结果表明

全流程对铱的回收率高于 92 %。利用建立的流程测定了丹麦地质标准参考物FC - 1

结果与推荐值吻合 ;测定了 3个日本地质标准参考物JSd - 1、JLk - 1和JMn - 1

铱的含量分别为 0 .10、0 .0 3、1.70ng·g- 1。

Abstract

Through 192 Ir radiotracer technique

the adsorption and desorption behaviors of iridium on AG1-X8 anion resin were studied. An AG1-X8 anion exchange enrichment procedure for iridium in geological samples was established

and the recovery of the whole procedure reached 92%. The Ir concentration in the Danish standard reference material FC-1 obtained by our procedure agreed well with the reference value. The concentrations of Ir in three Japanese candidate geological reference materials were determined by this technique.
