【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。更多还原

【Abstract】 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.更多还原
