摘要
本文研究了微分脉冲极谱法测定锰粉中微量铅的各项实验条件。选用KCL作为支持电解质。在此底液中,所得Pb^(2+)的微分脉冲极谱图,峰形良好,便于测量,其峰电位为-0.56V(相对Ag-AgCl电极,实验值)。可采用标准加入法测量。方法可靠,简便快速。
Experiment conditions for determination of trace lead in manganese dioxide using differential pulse polarography had been studied. Potassium chloride was used as supporting electrolyte. It was found that the peak potential of polarographic wave was -0. 56V (vs. Ag-AgCl electrode). Concentrations could be evaluated by standard addition. This method was simple and fast.
