摘要
本文发现Rh(Ⅲ)对KIO_4氧化α-萘酚酞褪色具有显著的催化作用,将这一新指示反应和流动注射分析技术相结合,首次建立了铑的流动注射分析方法.该方法灵敏、快速,操作简便,线控范围为0.020～0.40μg/ml,进样频率可达每小时64次.
In this paper, a new method has been recommened for the determination of rhodium by flow tinjection analysis.The proposed method is based on the catalytic action of Rh ( Ⅲ ) on the oxidation -of o-naphtholphthalein with KIO4.The method is sensitire, rapid and simple.In the concentratioa range of 0.020-0.40ug/ml, rhodium can be determined at rate of 64 per hour.
