薄层流动固定电位时安法,系在薄的小体积电解池中,用金盘作工作阴极,银-氯化银作阳极,控制于极谱极限电流电位,测定试样溶液由流动状态转换至静止状态时的时安电量。叙述了定量分析原理,电量-浓度方程式,实验方法,克服了电容电流及电极性能不稳定等干扰。灵敏度提高至10~(-7)M,噪音低,分辨力高,稳定,再现性好。与阳极解析伏安法相结合,优点显著。
Thin-layer flow of a fixed potential when the law, Department of thin small-sized electrolytic cells, the gold plate for the working cathode, silver - silver chloride as anode, control the polarographic current limit, the determination of the sample solution from the flow of state conversion Time to rest when the amount of electricity. Describes the principle of quantitative analysis, electricity - concentration equation, experimental methods to overcome the capacitor current and electrode instability and other interference. Sensitivity increased to 10 ~ (-7) M, low noise, high resolution, stable, good reproducibility. Combined with anodic analytic voltammetry, the advantages are significant.
