滴汞电极1.5次微分电分析法

The 1.5th Order Differential Electroanalysis with DME

本文采用TP803微型计算机计算了以滴汞电极为工作电极的1.5次微分电分析法理论方程中的有关特征参数;给出了峰高、峰宽和峰电位的定量关系式.用自制的示波新伏安仪进行了实验验证.结果表明,理论和实验结果一致.方法灵敏度和分辨率均高于线性扫描伏安法.

In this paper, the values of the hyperbolic function term in the equation of the 1.5th order differential electroanalysis with DME are calculated by using a TP803 microcomputer.The epuations of peak height, peak width and peak potential are given. Experimental results obtained with the oscilloscopic neovoltamograph made in our laboratory are shown to be in good agreement with theory. It is proved that this technique provides higher sensitivity and better resolution than ordinary linears sweep voltammetry.
