| 摘 要： | 本文研究了微分脉冲极谱法测定:氧化锰中微量镍的各项实验条件。并提出以试样分解后所产生的MnCl_2及所加入的适量NH_4OH—NH_4Cl作为底液。在此底液中,所得Ni~(2+)的微分脉冲极谱图,峰形良好,便于测量,其峰电位E_p=-0.56伏(对Ag-AgCl电极,实验值)可用标准加入法进行测定。方法简便、快速。

| Abstract: | Experimental conditions for the determination of trace nickel in manganese dioxide in differential pulse po-larography were studied. NH4OH -NH4C1 was used as supporting electrolyte. It was found that the peak potential of polarographic wave was -0. 56V(vs Ag-AgCl electrode). The conditions could be evaluated by standard addition. This method was simple and quick. |
