| 摘 要： | 铅、锡的极谱分析有多种方法,但各有不足之处。本文报道,在醋酸铵-铜铁试剂体系中,铅、锡可分别在峰电位为-0.82V及-0.92V处产生良好的导数极谱催化波,大量铜的存在不干扰测定。此法应用于铜合金中铅、锡的同时测定,获得了满意的结果,检测下限可达10ppb,回收率相对误差在10%以内。

| Abstract: | This paper is concerned with the polargraphic catalytic wave of Pb and Sn in the bottomsolution system of ammonium acetate-trietnanolam. ne-cupferron. Their peak potentials are-0.82V and -0.92V respectively. The determination will not be interfered by th existenceof a large amount of copper. When applied to simultaneous determination of Pb and Sn incopper alloy, this method enables us to get an ideal result, Its detection limit amount to 10ppb and the relative error of recovery is less than 10%. |
