本文主要研究了在熔融盐NH_4NO_3—LiNO_3—NH_4Cl中,熔融温度为125℃±0.5℃时应用交流示波研究无机物和有机物等交流示波极谱的特性。 实验(?)一步扩充了文献〔1〕所报导的研完工作,完成了被测物的Q值、最低检出浓度、定性分布图的绘制和熔融盐温度的选择。预示了在此熔融盐中定量分析的可能性,对Pb进行了定量测定。 实验采用Kaliskova电极为极化电极。实验证明在此熔融盐中使用它进行定量分析具有较高的灵敏度和较好的重现性,取得了较满意的结果。
In this paper, we studied the characteristics of AC oscillopolarography such as inorganic matter and organic matter using AC oscillometry in the molten salt NH_4NO_3-LiNO_3-NH_4Cl with melting temperature of 125 ℃ ± 0.5 ℃. The experimental (?) Step expands the research work reported in [1] and completes the Q value, the minimum detectable concentration, the mapping of the qualitative distribution and the selection of the temperature of the molten salt. This indicates the possibility of quantitative analysis in this molten salt and the quantitative determination of Pb. The experiment uses a Kaliskova electrode as a polarizing electrode. Experiments show that using it in this molten salt quantitative analysis with high sensitivity and good reproducibility, and achieved satisfactory results.
