文章主要研究了在熔融盐NaCl—AlCl_3中,熔融温度为160℃±0.5℃时应用交流示波极谱研完了无机去极剂离子Cu~(2+)、pb~(2+)、Cd~(2+)和Zn~(2+)等交流示波极谱的特性.实验进一步扩充了文献所报导的研究工作,完成了去极剂齐离子的Q值和pD值的测量及定性分布图的绘制,和熔融盐实验温度的选择.从而预示了在此熔融监中同时对Cu~(2+)、Cd~(2+)、Zn~(2+)和Cu~(2+)、Pb~(2+)、Zn~(2+)等定量分析的可能性,对Cd~(2+)进行了定量分析.本文采用悬汞电极和Kaliskova电极为极化电极.实验证明在NaCl—AlCl_3熔融盐中使用悬汞电极和Kaliskova电极进行无机去极剂离子的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 mainly studied the effects of inorganic depolarization ions Cu 2 +, Pb 2+, Cd 2+, Cr 2+ and Cr 3+ ions on the salt of molten salt NaCl-AlCl 3 at 160 ℃ ± 0.5 ℃ by AC Oscillopolarography (2 +) and Zn ~ (2 +) etc. The experiment further extends the research work reported in the literature and completes the Q value and pD value measurement and qualitative distribution map (2 +), Cd ~ (2 +), Zn ~ (2+) and Cu ~ (2 +), Pb ~ (2 +), Zn ~ (2+) and so on, we quantitatively analyzed Cd ~ (2+) .The hanging electrode and the Kaliskova electrode were used as the polarization electrode.It was proved that under the NaCl-AlCl_3 The quantitative analysis of inorganic depolarizing agent ions in molten salt using mercury electrode and Kaliskova electrode has high sensitivity and good reproducibility, and has achieved satisfactory results.
