选择阳极溶出伏安法和顺序注射分析法(ASV-SIA)，在可比较的条件下，考察了镀铋、锑膜玻碳电极对铅、镉离子的测定。令人感兴趣的是薄膜沉积的条件以及样品/载体溶液的组成，包括Sb(III)或Bi(III)和HCl的浓度。然后，通过优化的程序，可以在低MU L-1水平和ASV-SIA配置下测定铅(II)、镉(II)和锌(II)离子，并用两个电极对水样进行分析。
Anodic stripping voltammetry combined with sequential injection analysis (ASV-SIA) was selected to examine the use of bismuth- and antimony-film plated glassy carbon electrodes under comparable conditions for the determination of Pb(II) and Cd(II) ions. Of interest were the conditions for film deposition, as well as the composition of sample/carrier solutions, including concentrations of Sb(III) or Bi(III) and HCl. Then, by the optimized procedure, one could determine Pb(II), Cd(II), and Zn(II) ions at the low mu g L-1 level and ASV-SIA configuration with both electrodes tested on analysis of a water sample.
