Oscillopolaprographc Study of Some Inorganic and Organic Compounds in Molten Salt NaClO_4-LiClO_4

本文主要在160℃±0．5℃熔融盐NaClu_4-LiCiO_4体系中应用交流示波极谱研究了某些无机物和有机物的交流示波极谱的特性.实验完成了无机去极剂离子的Q值和pD值的测量及定性分布图的绘制和熔融温度的选择.对Z_n^(2+)进行了定量分析,同时指出了对Cu^(2+)、pb^(2+)、Zn^(2+)、Mn^(2+)和Fe^(3+)、Cd^(2+)、Zn^(2+)、Mn^(2+)等定量分析的可能性.实验证明,在此熔融盐中应用悬汞电极和Kaliskova电极进行某些无机物定量分析具有较高的灵敏度和较好的重现性.

The oscillopolarographic characteristics of some inorganic and organic com-pounds in molten salt NaClO4-LiClO4 are studied. The experiment extends the work reported, giving ionic q values of depolarizers and their minumum concentrations of detection pD, a diagram of the qualitative distribution of various inorganic ions. The paper gives an example of the application of the method in quantitative analysis of Zn2+. And it is possible for the applicability of simultaneous determination of Cu2+, Pb2+, Zn2+, Mn2+ and Fe3+, Cd2+, Zn2+, Mn2+ in molten salt NaClO4-LiClO4. In the molten salt applying hanging mercury drop electrode and kalis'kova electrode for the de-termination of some inorganic compounds can offer higher sensilivity and reproducibility.
