摘要: 本文提出了可逆逐级电子转移过程(n1=n2)的1.5次和2.5次微分电分析法(卷积伏安法)的理论公式,用计算机绘出了相应的理论曲线图,讨论了标准分离电位(△E0)及电子转移数(n)对电流~电压曲线的影响.选用氯化铜(Ⅱ)-氨水-氯化铵体系进行了实验验证,其结果与理论完全相符.

关键词: 逐级电子转移过程, 微分极谱法(卷积伏安法)

Abstract: The theories of 1.5th and 2.5th order differential polarographies for (n1 = n2) multistep reversible charge transfer are proposed and the theoretical polarograms were drawn with a computer.The effect of both the standard potential separation (△E0) and the number of electrons (n) on polarograms is carefully discussed.The reduction of Cu(Ⅱ) in 0.10 mol/L NH4+Cl-NH4+OH-was selected to test the theories and the experimental results were in agreement with the theories.

Key words: Multistep charge transfer, Differential polarography (Covolution voltammetry)
