摘要
本文利用锇(Ⅷ)对过氧化氢氧化酚酞啉显色反应的催化作用,首次建立了锇的流动注射分析方法,该方法快速灵敏、简便实用,已成功地用于实际样品的分析.
Abstract A new method has been recommened for the determination of osmium by flow injection analysis.The proposed method is based on the cataly-tic action of Os(Ⅷ) on the oxidation of phthalin with hydrogen peroxide.The method has a limit of detection for osmium of 0.020μg/ml and permits 60 deter-minations per hour.It has been applied to determine osmium in refined ore and chloride residue,and good results were ?.
