电位溶出分析法(PSA)与阳极溶出伏安法(ASV)可相媲美,且在某些方面还有其独到之处。例如,PSA法在测定中,不受试液中存在的表面活性物质的影响;在很低浓度的支持电解质溶液中可进行测定;在溶出过程中氧化速率恒定,分辨率可达到最优化;设计的仪器一般较为简便价廉。由于PSA法具有许多独特优点,近期已成为现代电化学分析法中的一个重要分 Potentiometric stripping analysis (PSA) is comparable to anodic stripping voltammetry (ASV), and in some ways it has its own uniqueness. For example, the PSA method is not affected by the presence of surface-active substances in the test solution; it can be measured in a very low concentration of support electrolyte solution; the oxidation rate is constant during the dissolution process and the resolution can be optimized; and the design The instrument is generally more simple and inexpensive. Due to the many unique advantages of the PSA method, it has recently become an important part of modern electrochemical analysis
