| 摘 要： | 利用５－Ｂｒ－ＰＡＤＡＴ对导出的线性扫描Ｌａｎｇｍｕｉｒ吸附可递电流的各阶导数公式在两种导数极谱仪上进行了实验验证。理论波形曲线和实验波形曲线进行了对比，验证了扫描述度和吸附电流各阶导数峰值、峰电位、峰间距的关系，以及峰高与浓度、富集时间及电极面积的关系，并求出不同扫描速度下的电流各阶导数峰值和电流峰值的比值。实验结果和理论值基本相符。

| Abstract: | The derivative equations of the current and the potential equations of deritrivevoltammograms for a reversible interfacial reaction where both the oxided and the reduced formsare adsorbed Strongly and a Langmuir isotherm is obeyed have been verified with 5-[(5- bromo2-pyridy)azo]-2,4-diaminotoluence(5-Br-PADAT) The relation ship of Peak height toconcentrstion, preconcentration time,area of electrode and the ratios of Peak valuces of differentderivative currents to the current have also ben verified. |
