卷积伏安法(新极谱法)是近十几年发展起来的一种新的电分析方法。由于它在电化学理论研究和实际分析中的优点,已引起电化学工作者的重视。弄清电子转移过程,可知中间体(自由基)发生的电位范围和稳定性,以及电极过程的可逆性等。Saveant等,推导出了可逆逐级电子转移过程(n_1=n_2)的半积分伏安法的理论公式,但此过程的0.5次微分电分析法文献中迄今未见报道。本文报告逐级电子转移过程的0.5次微分电分析法的理论和实验结果。理论对于电子转移数相同的逐级电子转移过程:
Convoluted voltammetry (neo-polarography) is a new analytical method developed in recent ten years. Because of its electrochemical theory and practical analysis of the advantages of electrochemical workers have attracted the attention. Clear electron transfer process, we can see intermediate (free radical) occurs potential range and stability, and reversibility of the electrode process. Saveant et al., Deduces the theoretical formula of semi-integral voltammetric method for the reversible step-by-step electron transfer process (n_1 = n_2). However, the literature of 0.5-order differential electro- This paper reports the theoretical and experimental results of the 0.5-DEMA for the stepwise electron transfer process. Theory for the same number of electron transfer step by step electron transfer process:
