摘　　要：文章主要研究了在熔融盐NaHSO_4-KHSO_4和LiNO_3-KNO_3中,熔融温度为130℃±0.5℃时应用交流示波极谱研究某些无机物的交流示波极谱特性。实验进一步扩充了文献所报道的工作。预示了Pb^(2+)、Cd^(2+);Pb^(2+)、Al^(3+)和Pb^(2+)、Cr_(3+)的定量分析的可能性。实验证明在此熔融盐中使用悬汞电极和Kaliskova电极进行某些无机物的定量分析有较高的灵敏度和较好的重现性。获得了满意的结果。The oscillopolarographic characteristics of some inorganic and organic compounds in molten salt NaHSO_4-KHSO_4 and LiNO_3-KNO_3 are studied. The experiment extends the work reported. And it is possible for the applicability of simultaneous determination of pb^(2+) and Cd^(2+) in molten salt NaHSO_4-KHSO_4, Pb^(2+) and Al^(3+) or Pb^(2+) and Cr^(3+) in molten salt LiNO_3-KNO_3. In the molten salt applying hanging mercury drop electrode and Kaliskova electrode for the determination of some inorganic compounds can offer higher sensitivity and reproducibility.
