摘要

提出平行催化体系的叠式循环阶梯脉冲伏安法和对位叠式循环阶梯脉冲伏安法，推导了这一方法的催化电流理论方程，研究了诸因素对电流的影响，通过实验证明了理论的正确性．发现无论是正向扫描或逆向扫描，是正脉冲还是负脉冲，催化电流皆为同方向，叠式循环催化电流相当于将单向电流叠加４次，因而灵敏度有较大提高，优于其它阶梯脉冲伏安法．

Abstract

The cyclic staircase pulse voltammetry(CSPV)and check potential additive cyclic staircase pulse voltammetry(CPACSPV)for the catalytic electrods system are presented. They can improve the shape of current potential curve to enhance sensitivity of determination. The theoretical catalytic current equations have been derived

and Ti(IV) H 2C 2O 4 KClO 3 system was used to verify these theories. The effects of parameters for the limit currents were studied in detail. The experimental results consist with the theoretical conclusions. The additive cyclic current is obtained by adding the pulse currents with the same sense four times

and the shape of the wave of CPACSPV is not affected by the values of pulse amplitude.
