【Abstract】 In this paper, the character of platinum sphere electrode with mercury film made by the vacuum plating has been Studied in anodic stripping voltammetry. The experiments shown that, in 0.1M KCl base—solution, there is a linear relationship between the peak current and concentration of copper and lead ion in 10^-6—10^-8M region. The characteristic of this electrode is stable and reproducibility is well. The electrode is successfully used determination of trace copper and lead in water.更多还原
