本文简要地介绍了一种新的相分析法——固态电活性电极伏安法的理论基础和定量分析条件,以及在金属相分析的某些应用。该方法的显著特点是不经分离,而把样品作为电极直接应用相在电化学反应过程中产生的电讯号进行分析,因而方法简捷、快速、节约、容易自动化、灵敏度较高,既可进行定量分析,又可进行定性分析。它可以解决萃取相分析、X射线相分析无法解决的某些问题。
This article briefly introduces a new phase analysis method - the theoretical basis and quantitative analysis conditions for the voltammetric determination of solid-state electroactive electrodes, as well as some applications in metal-phase analysis. The notable feature of this method is that the sample is analyzed directly as an electrode using the electrical signal generated during the electrochemical reaction without separation and thus the method is simple, rapid, economical, easy to automate, highly sensitive and allows quantification Analysis, but also for qualitative analysis. It can solve some problems that can not be solved by extraction phase analysis and X-ray phase analysis.
