Studies on Additive Cyclic Staircase Pulse Voltammetry Ⅰ.Simple Reversible Electrode System

本文提出循环阶梯脉冲伏安法和对位叠式循环阶梯脉冲伏安法,推导出简单可逆电极体系的电流方程,研究了峰电流与诸因素的关系,并进行了实验验证。

The Cyclic Staircase Pulse Voltammetry(CSPV) and Check Potential Additive Cyclic Staircase Pulse Voltammetry (CPACSPV) are presented.They can improve the shape of current potential curve to enhance sensitivity of determination.The theoretical current equations in simple reversible electrode process of these techniques have been derived,and Ti(IV) H 2C 2O 4 system was used to verify these theories. The effects of parameters for the peak currents were studied in detail.The experimental results consist with the theoretical conclusions.In the meantim, the CPACSPV is compared with the other CSPV, we come to a conclusion that the CPACSPV is far better.
