  • Published:1989-05-15

本文根据Luminol-K2S2O8体系中Au(III)和Ag(I)化学发光动力学性质的不同, 建立了金和银的时间分辨化学发光分析法, 研究结果表明, 利用时间分辨化学发光分析法同时测定混合物中多组分是可行的.

关键词: 金, 动力学, 银, 化学发光分析, 时间分辨率

Ag(I) and Au(III) were determine simultaneously by time-resolved chemiluminescence on the kinetic distinction of oxidation of luminol by the metals, in alkaline medium (pH 13) in the presence of K2S2O8 and ethylenediamine. Gold and silver can be determine at 0.01-1 mg mL-1 levels.

Key words: GOLD, DYNAMICS, SILVER, CHEMILUMINESCENCE ANALYSIS, TIME RESOLUTION
