摘要
本文首次发现Ru(Ⅲ)对KIO_4氧化α-萘酚酞褪色有显著的催化作用;将这一新的指示反应和流动注射分析技术相结合,建立了钌的快速、灵敏、简便的流动注射分析方法。将该方法应用于实际样品的分析,获得了满意的结果。
A new method has been recommended for the determination of trace Ru(Ⅲ) by flow injection analysis.The proposed method is rapid,simple and sensitive.The limit of detection for Ru(Ⅲ)is 0.010μg/ml and 65 determinations can be achieved in one hour. The method was applied to determine Ru in refined ones, and good result was obtained.
