计算机化的数字交流伏安法

Computerized Digital Alternating Current Voltammetry

电化学交流阻抗技术在电化学理论研究和测量上是十分有用的方法。Smith等人讨论了计算机辅助的交流极谱方法中许多人们感兴趣的问题,并曾使用快速富里叶变换技术同时检测多种谐波成分。近来,Bond进行了微处理器辅助的数字交流极谱仪的研究。迄今,计算机化的交流伏安仪方面的研究国内尚未见报道。本文在前文多功能仪器系统的基础上进一步建立了阶梯扫描交流伏安法并应用于实验研究,获得了满意的结果。

Digital alternating current voltammetry of computerized electrochemical instrumentation is described. It is found that the frequency of digital sine wave may reach to 1400 Hz. All available information of electrochemical experiments is memorized by instrument on-line, multi-current signal can simultaneously be detected in an experiment. This technique is applicable to electrochemical investigation and determination.
