摘要
在氢氧化钠介质中,过氧化氨氧化二溴苯基荧光酮,基于钌的催化效应,拟定了催化光度测定痕量Ru的新方法。本法的检出限为2.48×10 ̄(-12)g/ml,线性范围为0~15ng/25ml,方法灵敏,可用于矿石中Ru的测定。
The paper established a new kinetic spectrophotometric methodfor the determination of trace Ru based on the catalysis of Ru on thedecoloring of the oxidation of DB-PF by peroxide in NaOH medium.Thedetermination limit is 2.48 ×10 ̄(-12)g·ml ̄-.This method has been applied tothe determination of Ru in rocks and/or ores with satisfactory results.
