Simultaneous Determination of Some Ions With Close Polarographic Peak Potentials

本文根据极谱的基本原理,利用数学模型方法和计算机技术,提出了极谱波峰电位相近离子的同时测定方案。并对Pb-Sn合金镀液中的Pb^(2+)。Sn^(2+)离子进行了分析,结果回收率在93％～108％。可用于电镀工艺的研究和镀液的在线分析。

The determination of some ioas with close polarographic peak potentials is proposed, based on the polarographic principle using mathematic model and micrccomupter. Pb^(2+) and Sn^(2+) in electroplating solution of alloy is measured. The recovery is 93～108%, The method can be applied to the analysis in electroplating process.
