摘要

在回旋加速器上，用天然锑靶干法生产放射性药物Na

I注射液时

[1]

，需要监测分离流程中

I注射液中微量锑和铜的含量。

极谱法测锑大多在盐酸介质中进行，但铜有干扰

用微分脉冲阳极溶出伏安法同时测定了海水中的锌、镉、铅、铜、锑，但需用曲线解析器对重迭峰作解析处理，才能准确定量。我们以自制的聚四氟乙烯悬汞电极，配以国产F-78脉冲极谱仪，建立了微量锑、铜同时测定的灵敏、快速分析方法。以2

Abstract

Simultaneous determination of microamounts of antimony and copper has been investigated by self-made teflon hanging mercury drop electrode and F-78 pulse polarograph. This method was applied to Na

123

I injection with satisfactory results.
