A simple and inexpensive method for the estimation of stannous ion, Sn (II), in radiopharmaceutical kits is described. The method used is a potentiometric titration of Sn (II) in 1 N HCI medium, using potassium iodate as the oxidizing agent in an atmosphere of nitrogen. The apparatus includes pH meter, a platinum electrode, and a simple titration cell. Several commonly used radiopharmaceutical kits were analyzed for their Sn (II) content using this method. These studies indicate that the procedure can be used, as a routine quantitative test for the Sn (II) content of various 99mTc-labeled radiopharmaceuticals.
本文描述了一种用于估算放射性药物试剂盒中亚锡离子（Sn (II)）的简单且经济的方法。所采用的方法是在氮气氛围下，以碘酸钾作为氧化剂，在1N盐酸介质中对Sn (II)进行电位滴定。该装置包括pH计、铂电极和一个简单的滴定池。使用此方法对几种常用的放射性药物试剂盒进行了Sn (II)含量分析。这些研究表明，该程序可用作各种99mTc标记放射性药物中Sn (II)含量的常规定量测试。
