摘要： 本文利用Mo(Ⅵ)对H2O2氧化KI、Cu(Ⅱ)对K2S2O8氧化KI的作用分别测定了Mo(Ⅵ)和Cu(Ⅱ)。结果表明,此法具有直观、简便、仪器简单和快速等特点,测定灵敏度也有所提高,Mo(Ⅵ)可达10-8(mol/L)数量级,Cu(Ⅱ)可达5×10-7mol/L数量级。'

Abstract: This paper reports a catalytic kinetic method of analysis in which the alternating current os-cillographic bipotentiometric indicating technique is used to observe the change of concentration of a reaction product which is produced by the catalytic kinetic reaction. The experimental result shows that this method is more sensitive, more convenient and economic.

Key words: Catalytic kinetic analysis, H2O2 oxidation, Determination of Mo and Cu
