【摘要】 在H2 SO4 介质中钌对高碘酸钾氧化二溴硝基偶氮氯膦的褪色反应有明显的催化作用 .本文研究了该褪色反应的最佳条件及用于痕量钌的测定方法 .其检出限为 0 .0 2 μg·1 0mL- 1,钌含量在0 .0 2～ 0 .2 5 μg·1 0mL- 1范围内线性关系良好 .该方法已成功用于贵金属精矿和钌合成样中钌含量的测定 .更多还原

【Abstract】 A spectrophotometric method has been developed for the determination of Ruthdnium,based on their catalytic effect on potassium periodate oxidation of dibromo nitri chlorophosphonazo in H 2SO 4 medium.The optimum conditions of the reaction,thus,have been deternined.The determination limits was 0.02μg·mL -1 ,and the linear range was 0.02 0.25μg·mL -1 .The method has been applied to determine in ore with satifatery results.更多还原
