| 摘 要： | 高小霞等详细地研究了Eu(Ⅲ)-XO体系的极谱特性,用导数示波极谱法(ODP)检测下限可达5×10-8M。本文应用了Eu(Ⅲ)-XO的吸附特性将Eu(Ⅲ)-XO在悬汞电极(HMDE)上富集,使测定Eu(Ⅲ)的灵敏度提高约2个数量级。

| Abstract: | Anew high-performance trace analytical procedure with the voltammctric determination of Eu is described. The voltammetric method simply consists in the application of differental pulse voltammetry after prior intefacial accumulation by an adsorption layer of the complex Eu(Ⅲ)-XOat HMDE. In aqueous media the determination limit is 5 × 10-10M Eu and the linear range is 5 × 10-9--1 × 10-6M. |
