在回旋加速器上,用天然锑靶干法生产放射性药物Na~(123)I注射液时,需要监测分离流程中~(123)I与锑、铜分离情况,并要求分析Na~(123)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。Gillaing等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
In the cyclotron, the natural antimony target dry production of radioactive drug Na ~ (123) I injection, the need to monitor the separation process ~ (123) I and antimony and copper separation, and analysis of Na ~ (123) I Trace antimony and copper content in the injection. Polarographic measurement of antimony mostly in hydrochloric acid medium, but copper interference. Gillaing and other differential pulse anodic stripping voltammetry simultaneous determination of the seawater of zinc, cadmium, lead, copper, antimony, but need to use the curve analyzer for overlapping peaks for analytical processing, in order to accurately quantify. We have homemade PTFE hanging mercury electrode, coupled with domestic F-78 pulse oximeter, established
