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。
According to the basic principle of polarography, this paper proposed the simultaneous determination of similar ions at the polarographic peak potential by mathematical model and computer technology. Pb ~ (2 +) in Pb-Sn alloy bath. Sn ~ (2+) ions were analyzed, the recovery rate was 93% ~ 108%. Electroplating process can be used for research and online analysis of the bath.
