摘    要:用铋膜电极代替汞膜电极可避免环境污染。采用玻碳电极同位镀铋在酸性的KSCN介质中测定食盐中锌,结果峰形好、灵敏度高、峰电流值大,检测限为7.8×10^-8mol/L,线性范围为2.0×10^-6mol/L~1.3×10^-5mol/L,加标回收率为92.2%-102.2%。

关 键 词:铋膜电极  阳极溶出伏安法

Abstract:The environment pollution can be avoided by using bismuth film electrode instead of mercury film electrode. The sensitive adsorptive stripping peak of gine(lI) were found by stripping voltammetry. In KSCN solutions, the sensitive stripping peak of Zinc (Ⅱ) were optained and compared with that obtained using mercury film electrodes. The detection limits is 7.8 ×10^-8 mol/L. The change of the peak height appeared linear in the range from 2.0 ×10^-6 to 1.3 ×10^- mol/L and the rate of recovery is about 92.2% -- 102.2%.
Keywords:bismuth-film electrode  anodic stripping voltammetry  zinc
