摘要
在H2SO4介质中,微量铱的存在对KIO4 偶氮胂DBM的褪色反应有明显的催化作用,探讨了该褪色反应的最佳条件及微量铱的测定方法,检出限为0.1μg/mL,铱含量在0.1～1.0μg/mL范围内符合比尔定律.
A spectrophotometric methed for the determination of Ir(Ⅲ) on the oxidative fading arsenazo- DBM with KIO_(4) in acid medium . the methed offers the advantages of simplicity,rapidity,and sensitivity. Beer's Law is obeyed from 0.1 to 1.0 μg Ir/ml and the determination limits is 0.1 μg Ir/ml. The catalytic Reaction occurs in water phase.
